Chilly Weather Continues Dry Through Saturday Rain Likely Sunday
A strong upper air storm continues to rotate in counterclockwide fashion over the Eastern Great Lakes. We have been in the same spot here for the last couple of days with this storm not moving so the flow of chilly air continues today. We still remain in a sweet spot with clouds either well offshore or well to the west and north. Today looks to be a partly to mostly sunny day but it is going to be chilly with highs just in the low to mid 50s at best and some areas northwest of the coast might have a tough time breaking 50 degrees this afternoon. This is a solid 10 or so degrees below average.
Tonight will be another chilly night and another round of frosts and freezes mostly inland. Skies should be mostly clear and Thursday morning lows will be in the low and middle 30s with even some upper 20s inland and closer to 40 in warmer urban centers and along the coast.
Thursday begins moderating trend in temperatures as the upper trough pulls out of the Eastern US. We will see temperatures below average on Thursday but we will have sunshine taking highs to the upper 50s to around 60 degrees in most places.
Friday we will take temperatures up a bit more with some sunshine and highs reaching into the lower 60s in most places. The weekend starts with what I believe to be the better of the two weekend days. It will be a warmish day especially coming off this chill we have today. Saturday morning might start with some low clouds around and some patchy fog especially in cooler inland valles but we will go to sunshine rather quickly and highs will be in the mid to upper 60s.
Sunday hinges on low pressure developing off the Southeast coast of the US and then moving quickly northward up the coast. Right now there is a timing issue as to whether the rain reaches as far north as NYC and Southern New England by Sunday afteroon or whether it is slower and holds off until Sunday night, perhaps reaching areas in Southern New Jersey and Southeastern Pennsylvania Sunday afternoon. This low is a bit unusual and doesn’t look to be tropical, probably because it forms and moves northward rather quickly. For now we will go with cloudy conditions for Sunday with rain chances increasing in the afternoon from south to north. Highs will be just into the 60s with an increasing northeast wind. Rain will last into early Monday as the low continues moving north into New England. We will have to watch the track of this wave as there is a chance it could slide out more to the east and keeping rain out of the area Sunday.
