Very Humid; Isolated Afternoon Thundershowers

We remain in the tropical soup with morning fog followed by partial sunshine. Daytime heating will produce isolated showers and thundershowers mostly from mid-afternoon until early evening. We repeat the process Sunday. Monday is generally cloudy and less warm; widely scattered afternoon showers remain in play. A front arrives Wednesday evening from the northwest. It's a game changer with increasing shower/thundershower coverage ahead of the front and much cooler/drier air after the front.

Forecast Discussion

Very humid air covers the Southeast, but triggering mechanisms are lacking to produce rain. Daytime heating will be a trigger today and Sunday producing isolated afternoon and early evening showers and thundershowers today; widely scattered Sunday afternoon and evening.

A front will reach Virginia Sunday before fading off the map, but another front will "get the job done" moving across the Appalachians Wednesday night. Monday is even more soupy with widely scattered afternoon and evening showers and thundershowers. As the front approaches, it will tap moisture left from Nicholas and from the Atlantic increasing shower and thundershower coverage somewhat Tuesday. Then Wednesday looks quite wet, especially in the afternoon and early evening.

Fall officially begins Wednesday afternoon. Much cooler air arrives Wednesday night on cue. Thursday has clearing skies and cool temperatures as Canadian high pressure takes over our weather. Friday is pleasant and slightly warmer by afternoon.

Tropical Storm Odette formed yesterday off the Carolina Coast. It moves NE off the Mid-Atlantic Coast and will stay well off the New England Coast tomorrow. The former Tropical Storm Nicholas dumped copious amounts of rain on Louisiana during the last few days. It as lost an identifiably center, but it's moisture will drift slowly eastward. Another tropical disturbance is 1000 miles ESE of the Leeward Island and could become Tropical Storm Peter today. It will move WNW but turn north before reaching the U. S.
