This map shows the general area for thunderstorms today in green...while the yellow is the risk of severe weather. That risk covers..Maine..New Hampshire..Vermont..Western half of Mass., eastern NYS, Eastern Pa, NW New Jersey. The risk of tornadic activity will be highest across Northern New England. All of this due to a cold front that will end the heat and humidity.
Hurricane Humberto is well developed...estimated 85 mph wind. This storm will turn west...but longer range computers see a break in the Bermuda High and turn it north again...which would lessen threat to The U.S.
This global satellite shows Humberto off Africa (far right)....a new system in Yuchatan which could become INGRID. You can also see the cold front across northern U.S.
Once again..jet stream map for this weekend. The ridge holds out west...forcing the jet stream to come down from Central Canada to the East. Don't see this changing much....so once cooler air invades east...it will stick around. Be on the lookout for storms in Northeast today...later.
