A really quick post on the next few days.
Surface
chart and radar.
We still
have those persistent complexes of thunderstorms move over the Midwest. As has been the case for the last several
days these will drop south and east.
Looking at the radar we can see some of this is clipping Southwest
Pennsylvania. Most of this should stay
south and west of Pittsburgh, But the threat for isolated showers will be
there. The threat for showers will
extend across southern Pennsylvania into Maryland Delaware and Southern New
Jersey today, rain could be very heavy at times. Across the rest of New York
State and New England there could be a few hit and miss showers, with the
threat for a few thunderstorms, especially over New York State, these
thunderstorms should be non-severe.
Dewpoints
across New York State and northern and Central New England are very
comfortable. But those dewpoints are still in the 60’s and low 70’ s south of
there. The disturbance leaving the Ohio Valley, is going to be heading for the
Delmarva Peninsula, as this heads toward the Delmarva, humidity across
Pennsylvania and the Middle Atlantic will be dropping west to east.
We’re going to be dealing with a meandering boundary over the next couple of days, this will be dropping south tomorrow providing the region with a mostly dry Saturday with lower dew points and slightly below average temperatures, then the boundary will be returning on Sunday, as a stronger frontal system approaches and moves through. The leading warm front will allow temperatures and humidity levels to climb, along with the chance for isolated showers and thunderstorms. Then the trailing cold front will work through, bringing widespread scattered showers and thunderstorms. Some of these thunderstorms will be strong to severe this will be especially true across southern Pennsylvania, Maryland, Delaware into New Jersey. Rain could be heavy at times. The heavy rain could trigger urban and flash flooding.
The rain
will extend into Monday, but that cold front will clear out the humidity. As high-pressure
approaches, temperatures will be fairly comfortable for Tuesday and Wednesday.
But days look to be mainly dry. Then another frontal system will roll through
for Thursday into Friday.
