an upper level shortwave and flares of elevated frontogenesis tracks
through this morning with cloud cover and chances for showers,
mainly along and south of the us 24 corridor where more pronounced
low level moisture convergence is anticipated. a few diurnal showers
then potentially refire under the upper trough axis this afternoon
along any lingering lake boundaries or subtle inverted troughs.
overall coverage should be limited given poor moisture quality,
though a rumble of thunder cannot be ruled out if partial clearing
is realized.
cool, cyclonic, mid to upper level flow then remains locked in
thursday through early next week on the southwest fringe of a
southeast canada centered negative height anomaly. below normal
temps and mainly dry conditions will result, though subtle
flattening to the height field likely supports a warming trend and
better rain chances (30-40%) into next week. coldest of the air in
this regime still looks to be thursday through saturday, with friday
night likely the best opportunity for a solid early may
frost/freeze.

a moisture starved upper level wave and subtle elevated fgen
response will bring a few showers and chances for brief vis/cig
reductions to the terminals early this morning. high mvfr to
low vfr cigs likely settle in for most of the day otherwise
with a few diurnally driven showers not of the question during
the pm hours.
