Time and Day: 0900 Wednesday
The Snapshot: Heavy
rain begins today and continues through tomorrow night.
The Long Range:
Mixed snow and rain showers
with some clear periods are expected on Friday with another strong warm frontal
system developing over the weekend.
The Science: It is currently 32 degrees, 93% humidity with the
barometer at 1012mb and trending down. A
triple point frontal system (warm, cold, occluded) will lift up from southwest
today bringing with it heavy rain and rising
temperatures. A long stretch of moisture is being entrained
with this system so expect a ton of moisture for the next few days. The following cold front will begin to
filter in the cooler air late tomorrow
night. Freezing levels could drop to 4000’ or a bit lower by Friday night. There
could be a bit of snow accumulation on the
ground Saturday morning but it is not likely to stick around.
Long range models have
another similar wet, warm weather event expected to occur over the
weekend. Things begin to dry out early
next week as the high pressure developing
to the south should begin to nudge the moisture north.
