Wet and Chilly Pattern In Store For Most..

Not sure if any one has noticed the same thing that we have seemed to notice and that is that it seems that we awfully quickly have gone from what was a warm to very hot pattern to an unusually early fall type air mass. September so far seems to be a completely different month compared to the prior months..

Now lets show you what we are talking about before we get into the very above image. Lets look back at July And August across the Northeast Region..
You can clearly see that these two months were pretty much well above normal in the Northeast but from Central PA to the southeast it was normal to below normal..
Fast Forward to september...
Here it looks pretty much like we are almost back into looking like a warmer pattern with the above normal temperatures but ..we need to look at the last 14 days to get the brighter and full spectrum of the picture..
The last 14 days..NOW that is the big change we were talking about ..but look at the last 7 days..
Even more below normal especially Ohio region into eastern KY and parts of West VA. Pretty stark drop and contrast in temperatures compared to even just the first week of September...
So we have gone from a warm to hot weather pattern to a chilly air mass and a air mass that will be becoming more increasingly wet across the central part of the nation.

Now as you can see we have a cold front dropping down from the north but to the south of that we also have another frontal feature with a warm front extending south and this low pressure is going to more or less be moving towards the east at the same time the cold front will be dropping to the south and this is going to increase the likely hood of rain (some of it heavy) and the potential for severe thunderstorms over the next 72 hours.

From there this frontal system moving in from the NW will be making its way into eastern PA in the over night hours on tuesday after midnight (which would mean early wed Morning)..


Over all we are expecting any where from 1 to 3 inches of rain with isolated areas up to 4 inches of rain. Many of these areas need the rainfall as they are having harsh droughts at the present time.
As we mentioned this will be moving into E PA and NJ by late tuesday night which will introduce a chance of heavy rain in those regions as well..

It does appear however that ridging in the long range could build back west from the Central Atlantic ridge to the Western Atlantic ridge into the Eastern US so if that be the actual outcome we could see warmer weather return just in time for October...
