Thunderstorms This Evening Busy Weather Week Ahead Threats All Week Long
We are watching to see what comes out of Central Pennsylvania this evening as we see the warm sector setting up this afternoon across Southern New Jersey and Southern Pennsylvania and points southward into Maryland. The boundary zone with clouds runs from New England west southwestward into Pennsylvania and Ohio.
You can see the pulses running along that boundary clearly on the regional radar with one moving through New England and now a second one that is approaching from the west. The Storm Prediction Center has indicated a 40 percent chance for a severe thunderstorm watch from the Southern Half of New Jersey southwestward into South Central and South Eastern Pennsylvania to Maryland. Eyes will be on the radar going into this evening.
LOCAL RADAR NEW YORK CITY
This is going to be a busy week with thunderstorm threats all week long. The upper air jet streams shows several short waves marching across in a jet that is moving air from the Pacific northwest, into the Plains and straight to the East coast.
Think back to a couple of weeks ago when we had that frontal boundary lying east west across the US and we have pretty much the same scenario again. As each wave goes by the boundary buckles to the north and then to the south. As each one of these short waves goes by we get the threat for showers and thunderstorms.
This is going to mean substantial rain in some areas and of course driven by thunderstorms this means expect variability in rainfall amounts. Several inches spread out over the course of this week is certainly doable and there will be a bulls eye zone just to the south of that frontal boundary somewhere in the Middle Atlantic States.
The pattern does look to break late this week and just in time for next weekend as the pattern relaxes and an upper ridge starts to build in the Eastern US beginning next Saturday. This would come just in time for the first weekend of the summer season.
Some of the longer range models suggest that the break will be temporary as the jet stream in the East may try to come back southward from Canada at months end and as we begin July. There is still no sign of prolonged heat for our area anytime soon.
