We currently have a powerful storm system entering the Plain states, which expected to produce the biggest severe outbreak of the season thus far tomorrow from NE Texas all he way to portions of Minnesota, meanwhile upper level ridging developing over the east and a negative NAO signal are working together to slow down the weather pattern with a cutoff low developing over the southeast, the interaction of all these features will lead to a very active and stormy 5-7 day period for the forecast area
The developing cutoff low will send upper level disturbances our way , the first of which tomorrow , will produce scattered widespread showers , this disturbance will be a warm front which will cross the are on Monday, so while Sunday will be a cool raw day , a more mild and humid air mass will begin to move in Monday and really tae over though much of the week, the mild humd air mass with a southwest flow along with disturbances coming from the southwest will lead to the chance for sowers, thunderstorms and downpours each afternoon, each of these distrbances will have to watched for potentially producing stronger thunderstorms
Much of the activity looks to be scattered Monday through Wednesday, so some of the area could remain overall pretty dry while others get rainfall measured in inches, but as a strong cold front associated the storm system over the Plains , along with the cutoff low come north and east , widespread showers and storms are expected Thursday, Friday and potentially into Saturday ,very heavy downpours and localized flooding will be possible
Temperatures on Sunday will be stuck in the low to mid 60s with cloudy skys, showers and a raw east wind , rising to the upper 60s to 70s Monday then mid to upper 70s towards the coast and higher elevations of NE PA to low to mid 80s for the rest for the reminder of the week depending on the warm front, if it stays to our north which expect given ridging over the east , then these warm temps can be expected along with higher potential for strong to severe storms , if it sags back south like some models suggest it would be cooler Wednesday and beyond with more cloudy showery raw weather rather than breaks in then clouds with periods of stormy weather and again warm muggy temps, lows in the upper 50s to mid 60s are expected ,
Either way a very active week is on the way and many areas il see ao of rainfall, general range of 2-4 inches is likely as of now area wide between Monday a Saturday , pinpointing areas of heaviest rain totals impossible as this will depend were thunderstorms occur most frequent, updates on this throughout the week!
