Good afternoon everyone. For the past couple of weeks, I've been talking about the possibility of a pattern shift going on around mid-May, and it looks as if the pieces are coming together for it. It's very important to understand the language I'm using here, where I'm using the word "shift" and not "change".
The pattern itself remains active and with cool air still available. However, a shift of our systems northward by a few hundred miles, will make a difference in terms of getting some milder/warmer air into our area; and for a couple of extra days at a time.
SATELLITE
Today is a done deal as far as any real chance of warming up much. Unseasonably chilly air is here, with gusty winds and useless sunshine. Look for those windy conditions to continue, and we'll be lucky to reach 50, if that.
REGIONAL RADAR
The good news is we modify quickly for Mother's Day tomorrow and stiff westerlies will allow us to get into the 60-65 degree range with full sunshine.
LOCAL RADAR NEW YORK CITY
Monday we play the game again with yet another system bringing the possibility of showers and storms, and near 60 degree temps.
Sunshine and breezy weather follows Tuesday and Wednesday with 60-65 degree weather, then the transition begins Thursday and Friday.
LOCAL RADAR PHILADELPHIA
A warm front will enter the picture on Thursday with the slight chance of some light rain, and mid to upper 60's breakout across the area. Some 70's are possible Friday, and depending on if the milder airmass can hold or not, next weekend may see temps ranging from the low 70's to near 80.
When we start to see these changes, the marine layer typically becomes a factor, especially when ocean temps are cooler than average. If we can hold off the marine layer to parts of New England, 70's and near 80 temps could be a common sight to finish off May. That being said, the pattern remains active and fast-moving, so there will be clouds and showers along the way.
Please note that with regards to any tropical storms or hurricanes, should a storm be threatening, please consult your local National Weather Service office or your local government officials about what action you should be taking to protect life and property.
