A low pressure system is sitting between New Mexico and Arizona causing moderate precip, but high pressure in the center of the nation is stalling not just the low but the front as well, which will end up bringing almost an inch and a half of rain to much of the state, ironically more in the deserts in the south portion of the state.
The second area is in Louisiana where yet another area of low pressure is constantly drawing up moisture from the Gulf and dumping over an inch of rain to most of the state.
Finally the big weather-maker in the US, a very large low over Florida, along with not only a stationary front extending into the Atlantic but crosswinds coming from the Great Lakes will create a deluge in the mid-Atlantic seaboard today. West-central VA and NC will get what NM is getting today, at least an inch and a half, but western SC into the Delmarva Peninsula will see over 2", with the biggest rainfall in eastern NC seeing upwards of 3", most of it falling in the morning.
Like yesterday almost the entirety of the center of the US from mid-Texas into ND will see sunshine today with no precip, as always California will be basking in sunshine, and even places like Washington state which usually have no shortage of passing showers will be in the clear.
Next up the high pressure over Nevada will keep any clouds away, though with 104° temperatures today I'd at least want some clouds to hind behind.
Finally ending in the NY Metro area, even though there's a slight chance of showers and thunderstorms in the mid-afternoon, the day will actually start off partly sunny before the clouds start to roll in closer to noon. Going farther north into New England they'll get a decent well-deserved break for the daytime after getting scattered showers and thunderstorms all last night.
Skipping past the weekend I'll just leave with this long-range news: Tuesday will be the start of a sunny trend, so look forward to that.
