Map above for late today. Weak low brings grey/damp weather to Mid Atlantic and Northeast. Lingering showers in southeast. Rainy for No. Plains and Rockies. West coast is dry except for Pacific Northwest.
Satellite shows front along East Coast with clouds and some rain. Powerful system in Plains...will head east and reach the East Saturday followed by a touch of fall for all.
Map above shows front along east coast for Saturday a.m. Cool air floods much of The Nation. Below...high temperatures expected for Sunday. Be safe.
System near Bermuda will bring rain and wind to Bermuda..but tropical development will be slight. Hurricane Rachel off Baja...will spin around and slowly weaken. Front in East will bring some unsettled weather there.
Hurricane Rachel still looks healthy with a good outflow. Winds of 75-80 mph...but she should weaken and just meander before moving west.
Map for late today...shows front over Great Lakes...bringing some showers from there to Northeast. Old front in southeast will cause showers there. Fronts in Rockies and west will bring bands of showers....all of which will march eastward this week. No big deal. So September should go out and October should come in on a seasonable note. Be safe....later.
October starts next week and reaching 80 degrees will soon start to become a statistical improbability. This last weekend of September however will see a few areas reach over 80. A tall ridge across the Eastern US brings sunshine and warm air through the weekend from the Northeast, out to the Midwest.
On the infrared image above, the air flow through the jet stream can be seen moving down the west coast, and up north through the Rockies into the southern Canadian region and continuing eastward into the Atlantic. High pressure along the eastern part of the jet will be settling in for the next few days, resulting in the aforementioned sunny & warm weather.
In the Southeast, another wet weekend is on tap with moist, unstable air along the Gulf Coast moving east-northeast through the weekend. Scattered rain showers and thunderstorms are possible along the immediate Gulf Coast today and will shift into Georgia and the Carolinas for Sunday and Monday before drying out mid-week.
Out west, temperatures are expected to heat up a bit as a ridge moves in behind the trough currently building out in the region. In Southern California, 90's could be reached late week with areas along the San Francisco bay area reaching over 80 to start October.
Above...satellite of Rachel south of Baja. The expansion of "black" indicates intensification...so expect hurricane center to "up" her strength later this a.m. Below...expected track of Rachel...which could pose a threat to Baja again.
Map for late Saturday showing high pressure covering much of The Nation. Wet weather Rockies...Gulf coast.
Above...you can clearly see the jet stream flowing across the Northwest. The other jet is along east coast...and in between...nice and warm.
Above...satellite of the tropical Atlantic. Disturbance in the bottom right is being watched for development. Weather or not...have a nice safe weekend.
Band of rain along east coast will push offshore tonight. Much of the rest of the nation except Northwest will be fair and warmer right into the weekend.
Tropical Atlantic is quiet....but there is a couple of disturbances that bare watching but not promising.
Tropical Storm Rachel - south of Baja, Ca. moving west. Looks very healthy but should stay away from land areas.
Low pressure along Mid Atlantic will bring rain and move out tonight. Showers will continue Pacific NW....and Florida.
The above map shows how nighttime temperatures will average for the next week. Remember...these are overnite. 10 to 15 above the average.....so many of us will not have to turn the heat on. Stay safe....later.
Satellite shows conveyor belt of moisture moving from Fla., to Mid Atlantic....this rain should reach southern New England Thursday. Powerhouse storm east of Vancouver, B.C. will bring wind and wet weather to The Northwest,
Early morning Wednesday radar shows rain over Carolinas marching north. This will give the Mid Atlantic heavy rain...and they can use it.
The map above for late Thursday....shows the low along Mid Atlantic coast with rain. Unsettled in Northwest and southern Texas.....rest of The Nation...no problem.
Above...amounts of rain which will fall thru Thursday. The brown indicates 1.50"....which I think is a bit much and this could be overdone for those areas...nevertheless...first significant rain in some time for those places.
Above...high temperatures expected for next Wed., Oct. 1st. Notice how cold it is in the Rockies....a sign of things to come ? Be safe. Later.
Above....blue streak along East coast....moisture that could turn out to be heavy rain for mid Atlantic...but only a glancing blow to southern New England by Thursday. Strong storm off west coast of Canada will change the pattern and produce warmer weather for Eastern half by weekend.
Map for late today: low off Georgia could be the troublemaker for Mid Atlantic mid week. Elsewhere...not bad.
Amounts of rain Wednesday into Thursday. Notice....southern N.J. thru Delaware - 1- 2" of rain while NYC will see less than 1/4". Interesting ?
Map above shows how temperatures will average from this weekend into early next week. Map below...continues that trend thru most of next week.
Tropics are quiet on both coasts....but don't think that's it for the season. Be safe....later.
While Fall arrives around the same date each year, the weather doesn't always comply. This is the same for both the meteorological Fall (first of the month) as well as the seasonal Fall (22nd-23rd). However by sheer coincidence today weather-wise we actually are seeing a complete change in the seasonal weather as relative humidity will be dropping into the 40-50% range and temperatures dropping in similar fashion.
Again, there is a difference between a normal (astronomical) season and meteorological seasons. The normal Spring, Summer, Fall and Winter that many people know coincides with the movement of the Earth around the Sun and falls on the 21st, 22nd, or 23rd of the month depending on the year. It's different because of the extra quarter day that we experience every year, fixed by what we know as leap years and. During these normal seasons, the Summer and Winter solstices the Earth's axis faces the sun and either the northern or southern hemisphere's axis faces the Sun, and the Spring and Fall equinoxes they're perpendicular to the Sun.
While that has to do with cycles of solar body revolution, meteorological seasons deal with the cycle of annual temperature cycles, hence why they start 20-22 days earlier. However this has to do with global variations and as such may not actually coincide with regional average temperature cycles.
So which one should you follow? Personally I always go with the normal seasons as weather is always in flux and their deviations rarely coincide as well with the cyclical definitions. That and climate is changing so much that it may not be accurate any more.
The map above is a bit misleading as it will change dramatically to the east as the day goes on. Why? This:
That left-most cold front is the key in the temperature change. It will be making its way through the Northeast and the Atlantic Seaboard throughout the day. That being said, much of the center of the nation is still in the path of sunshine and will continue to see that as well throughout the week. In fact if you look across the entire US for the next 5 days and average out the chance of precip it would be a tiny 4% chance, cloud cover only reaching into the 20-30% range.
Finally a look at the current tropics. While the Atlantic has been very quiet this entire season with only 5 named storms and 4 of those hurricanes, the Pacific has been stealing the show with 17 named storms, 12 of those hurricanes and 8 of those being major hurricanes of category 3 or higher, 5 category 4 and the strongest Hurricane Marie a category 5 with 160 mph winds. In fact it's been so busy that at one point there were three hurricanes active at once, all within 2000 miles of one another.
Right now however we have Tropical Depression Polo, once a category 1 hurricane, that is moving offshore and slowly dissipating. Another storm though is currently south of Mexico and has a 60% chance of forming into a hurricane over the next 48 hours, and a 80% over the next 5 days. That one is slated to be named Hurricane Rachel once it intensifies.
The Climate Prediction Center did in fact call for a below normal season, and on average across the board there were predictions of 12 named storms, 6 of those hurricanes and 2-3 of those major. Right now we're just under halfway there for total storms and 2 away for both regular and major hurricanes.
The Pacific was of course higher for the average of predictions with 15 named storms, 7-8 hurricanes and 3 of those major. Again right now we're WELL above that average so that deserves a look at the record high activities:
In 1992 we had 28 named storms, 16 hurricanes and 10 of them major. At 17, 12 and 8 we're close to breaking that with still more time left in the season.
The Autumnal Equinox is this upcoming Monday, September 22 for the the United States (officially September 23, 02:29 GMT). Conditions will be nothing short of perfect following this weekend which could see showers on Sunday as a cold front moves through.
For today, high pressure is in control of the Northeast, though is being pushed offshore by the aforementioned trough into Sunday.
The trace of the cold front can be seen in the clouds dipping through the western Great Lakes region this morning through Chicago and into Missouri. In the Southeast lies another disturbance that is bringing the threat for rain and breezy conditions to the coastline. This weak low will move north and mesh with the trough that moves by on Sunday and continue to bring showers mainly over the ocean waters.
Following the cold front, high pressure takes full control through the week with dry weather for much of the country into next weekend as the air starts to get a bit chillier each night with October not far away at this point.
You don't have to be a meteorologist to see the powerful jet stream off the west coast. This may be the first sign that a pattern change is underway. It would result in wet stormy weather for Pacific Northwest and warmer weather east. The blue/green in Dakotas is a cold front which will pass ff the east coast Monday.
The map above reflects the upper air for late next week. It shows the jet stream along the west coast and then a ridge or high pressure over the East. So as fall comes in..things will get warmer east and cooler west.
Map above is for Late Saturday. Cold front pushing thru Great Lakes may result in some severe weather there. Watch low off Southeast coast...it could mess things up as far north as New England with low clouds...fog...drizzle.
Yellow area above indicates area threat for severe weather on Saturday.
Above...Atlantic tropics...quiet...with one disturbance off Africa. Below...a close up look at that disturbance....does not look too organized now. Have a nice weekend...be safe.

Above...map shows how high temperatures will average thru Sept. 25th. Be safe...later.
Hurricane Edouard in Central Atlantic with 85 mph + winds
will only threaten marine interests.
Hurricane Odile - Southern Baja Ca., with 120 mph winds. Will move north and slowly weaken but will bring wet weather to the southwest.
Aside from the tropics.....a cold front over the Great Lakes will bring a few showers from The Lakes east to Northeast over the next 24 hours. Another front in Central Canada will bring a re-enforcing Canadian air mass to same places late this week.
Map valid for late today shows those 2 fronts....and not much else. Not complaining.
This map shows how daytime temperatures will average for the next week. Blue = below....red - above....purple = near normal. Be safe.
