Widespread Rain Coming Later Tuesday Into Early Thursday Cooler Air Follows
WEATHER IN 5 PODCAST SUNDAY SEPTEMBER 27, 2020
SUNDAY MORNING 9/27/2020 JOE & JOE WEATHER SHOW PODCAST
Our warm humid weather continues overnight and on Monday thanks to strong high pressure to the east and a southerly flow along the east coast that at least for now is filled with low level moisture but not much else. Low clouds and some patchy fog will develop overnight into Monday morning much like the last 2 mornings. Then we will burn some of that off Monday as the sun tries to break through. This time of year the lowering sun angle and shrinking daylight make that a tougher proposition. Lows tonight will be mostly in the 60s except for a few 50s in the coolest spots. Monday’s highs will be in the mid 70s to around 80 degrees or so in the warmest spots. It is a messy looking satellite view this evening with patches of clouds and some breaks in the mix but the radar is very quiet in the Northeast and Middle Atlantic states.
Weather conditions begin to go downhill on Tuesday. A front approaches the coast and slows down. It will come to a halt to our west and then we will begin to see the impact of a strong upper trough in the Great Lakes to the Gulf states as moist tropical air moves up the East Coast.
Waves of showers will begin developing in the Southeast US and then moving northward up the coast. The first round later Tuesday into Tuesday evening will be patchy but then more numerous showers and possibly a thunderstorm will be in the mix for Tuesday night into Wednesday morning. This will push the front further east and then a second wave of heavy rain and possible thunderstorms comes through Wednesday night into Thursday morning. This will be the final wave of low pressure moving through.
Rainfall amounts in total will be significant and this really an ideal scenario. If we can spread out 2 to 3 inches of rain which is what the GFS shows, it will soak into the ground rather than run off. This should put a dent in the serious to extreme drought conditions that exist in New England. The stripe of several inches of rain runs from Georgia to Maine. Cooler drier air follows and we will be going into a stretch of below average temperatures in the long range. Weather conditions should start to improve later Thursday. Friday we will see another front pass and behind that the coolest air will settle in over next weekend. This probably means daytime highs in the 60s and nighttime lows in the 40s to near 50.
