We are beginning to see a weather pattern developing and locking in that will bring cool and below average temperatures and developing stormy conditions to the forecast area.
The first piece of this puzzle came through last night in the form of a cold front with scattered showers and thunderstorms and a shot of Canadian air right behind it for today and tomorrow, windy northwest winds of 15-25 with gusts 35-40 will continue today and breezy conditions will remain through the day tomorrow with highs both days generally in the 50s for most of the area, upper 40s to low 50s over NE PA , mid to upper 50s elsewhere and lows tonight will be in the 30s for most of the area with a few low 40s in extreme south and east locations tomorrow nights lows will be similar but a few degrees warmer with lows generally in the mid 30s to low 40s
Friday we will begin to moderate a bit with highs in the mid 50s to low 60s area wide, generally right around or just a bit below where we should be. A cold front will approach Friday night and especially Saturday with increasing clouds and scattered showers developing , with a southwest wind temperatures will moderate a bit more to near to slightly above normal temperatures for Saturday with highs in the upper 50s to mid 60s for most, can’t rule out a few lower 70s especially if there’s any delay with the clouds and showers
As low pressure develops along this front the threat for scattered showers will persist into Saturday night and early Sunday , most activity will be scattered and light during this whole event but there could be some isolated thunderstorms or heavy downpours in those lucky spots and there will likely be some breaks of sunshine on Saturday , the system will clear out Sunday with temperatures falling back to the mid 50s to low 60s for highs.
We will see a brief break in stormy conditions Sunday and during the day Monday but a storm system will likely develop over the Plains and “cut off” from the steering currents aloft. This will lead to the low pressure system only very slowly crawling eastward and more or less meandering around the forecast area through much of the week next week.
Details are still sketchy but it appears clouds will be on the increase Monday with rain filling in somewhere between Monday night and Tuesday afternoon
Once the rain fills in it will not be moving out anytime soon as this low persists over the east
We jump 2 days in advance all the way to Thursday afternoon and rainfall persists over the area
And even into Friday the rainfall may continue, it does appear the storm should finally clear the northeast by next Saturday
Now with this all being said , next week will not be a washout per say with steady rain all day everyday , but more likely the rain will come in waves of steady rain with breaks in between and so while an immense amount of rain is very possible with this type of event it wont be all falling at once but over a 4-5 day period . It does look like either way you slice it a very stormy week is setting up because even in between these waves of rain will be scattered showers , drizzle and a raw cool easterly wind. Flooding will likely become a concern as well. These types of set ups are very volatile and tricky so I wont be able to into much detail on rainfall amounts and that kind of thing until the weekend just keep in mind that there is increasing chance of this storm hitting us and it will likely make for a very wet, stormy and cool week next week.
