You can definitely tell we are in a full swing transition from summer to fall with all the recent temperature swings and cool shots, this week will feature pretty extreme temperature swings as well as the autumn pattern begins to take over but summer still wants to fight back a bit
While Saturday was rather mild, Yesterday a cold front came through which introduced us to another polar air mass with a chilly night last night and temperatures today struggling well below average , but as we can see on the satellite this trough is already moving out and will give way to ridging coming in from the west in this progressive pattern, this ridge will pack quite a punch in terms of one heck of a warm up starting tomorrow and lasting through Thursday
As the trough begins to move away and ridging moves east winds will turn from north to south tonight ushering in a warmer air mass so lows tonight are generally expected to be in mid 50s to low 60s for most locations, a far cry from the widespread 40s just last night
As a southwest flow becomes established , a hot humid air mass will be transported from the Gulf of Mexico up the east coast starting Tuesday , with high temperatures in the lower to mid 80s for most places with notably higher humidity , the warm spell will peak out on Wednesday with full sunshine and with temperatures near 20 Celsius aloft, it will likely produce widespread lower to mid 90s for highs!
The summer heat wont last long though as a potent cold front will cross through the region on Thursday, likely later in the day which will still make Thursday rather warm and humid with lower to mid 80s for highs but humidity will make it feel warmer , there will also be the potential for scattered thunderstorms in the afternoon and evening hours with heavy downpours and gusty winds possible, there could be some strong thunderstorms but for the most part a widespread severe event is unlikely once again , as the northeast continues to escape this severe weather season.
Starting on Friday and especially Saturday a potent trough is expected to move into the northeast making for a much cooler and even chilly end to week and weekend, where highs will struggle in the 60s for many and lows in the 30s possible over the interior , 40s elsewhere through the weekend. Friday will be the warmest day with widespread 70s for highs expected.
It does appear as we get past this warm up that what we see this weekend will become the dominant weather pattern , with a trough settling over the east and more in the way of prolonged polar air masses rather than just these quick hitting ones and the constant up and downs also look to settle down after this week as autumn takes over.
I will likely come out with an Autumn 2013 forecast in the next week or so for the forecast area!
