Time and Day: 0700 Wednesday
The Snapshot:
Windy this morning with sunshine
expected later today. Light mixed rain
and snow arrive tomorrow afternoon with a
showery pattern on Friday. Snow can be
expected over the weekend.
The Science
Current Observations: The clouds have
moved out this morning with clear
conditions being observed. The
temperature is 19f, the RH is 92% and the barometer is at 1022mb and has been
slowly falling. This morning’s satellite
radar has some very light spotty showers to the southwest and clear skies to
the north and east. The easterly winds
have been constantly blowing at 10-15mph.
The Forecast: The clearing is due to the warmer southerly
flow that has begun to erode the cold inversion
air. Morning fog can still be expected just prior to sunrise, with some
sunshine anticipated later today.
A low-pressure trough digging deep to the south will bring warm moist
southerly flow to the region starting tomorrow. The mixed rain/snow game will begin with
intermittent showers expected on Friday.
Freezing levels are expected to rise above 5000’ with some east flow
effect.
The Long Range: A cold front arrives on Saturday, lowering
freezing levels and producing some snow leading into Sunday. The rain vs snow game will commence next week
as more storms enter the region from the south-west.
