Surface Chart and Radar
The High
pressure is starting to exit ahead of the slow-moving cold front; this is going
to lead to increased cloudiness and then rain showers and thunderstorms. Today
is going to be unseasonally warm. Ahead of the front will be increasing 15-30
mph and becoming gusty with gust of 35-45 mph possible.
Looking at
the radar, we can see some spotty showers moving into western parts of our
region as well as a few over New York State and northern New England. But the
air is dry, so some of this isn’t reaching the ground. For Northwest
Pennsylvania and parts of New York State and northern New England; the rain
will be become more widespread, and the intensity will increase by during the Tuesday
afternoon and especially Tuesday night into Wednesday with localized heavier
downpours quite possible. This afternoon and evening will likely see scattered
thunderstorms develop. Some of these could be on the strong side. The heavier
rain will make it to Southwest Pennsylvania and Pittsburgh late tonight into
Wednesday.
Storm Prediction
Center (SPC)
The SPC has
a Marginal Risk for strong to severe thunderstorms this afternoon and evening.
The main risk will be strong damaging winds, with gust of 60+ mph. But there is
also a danger for some hail, heavy downpours, and possibility a few tornadoes,
but the tornado risk is very small.

The rain and
a few thunderstorms will move into eastern New York State late Afternoon and especially
this evening
As for Wednesday, it’s going to stay windy with gusts 30-40mph., as the cold front slowly advances south and east rain and embedded thunderstorms will develop across eastern Pennsylvania and especially Southeast Pennsylvania and the Northern Middle Atlantic This will continue during the afternoon before tapering off to more in the way of scattered showers by Wednesday night. The rain looks to make it into Southeastern New England during Wednesday afternoon and Night. As low pressure develops along that front Thursday, we could see some light rain or rain showers redevelop on Thursday, especially Southeast Pennsylvania and points east. The rest of the region will remain unsettled for Thursday.
The weather
is going to remain unsettled for Friday and through the Mother’s Day Weekend,
as we see several weak shortwaves move through. But it won’t be a washout; I
expect the showers to be more isolated than not. Rain chances will increase for
Sunday night and Monday as a stronger cold front works through. Then High
pressure will move in for Tuesday, producing more in the way of tranquil weather.
I really don’t
know how these daily weather posts are being received. Not too many of y’all
are reading them.
