February 12, 1999
Well, the forecast that I have posted on 2-9-99 was looking good up until last night, hence
the reason for my page not being updated. However, there have been some HUGE
differences in the computer models over the past 24 hours. The two pieces of energy that
were forecast to remain separate are beginning to gel and are zipping off into Canada.
However, there is still a small piece of energy set to round the base of the trough after it
moves through. In short, it may form a wave along the front, but will probably be well to
our east and not affect us. Also, the system is more progressive than originally thought, so
any chances of snow for tomorrow night into Sunday are virtually nil, but we may still see
a period of snow tonight after the cold front presses through. In technichal terms, this is
known as post frontal precipitation. Oddly enough, that is where most of the moisture is
with this system as opposed to out ahead of it. So, after we reach the mid 60's today for
highs, the cold front will barrel through, accompanied by rain, high winds, and maybe even
a thunderstorm. But, don't let today's warm weather fool you. Temps will drop like a rock
after the front pushes through (sometime between 5PM and 10PM). Thereafter, as rain
and showers continue behind the front, the dropping temps wil interact with the rain and
cjange it over to a brief period of snow probably before midnight. Should not be a big deal
because surface temps are very warm from today and little accumulation is now expected.
Tomorrow the skies will try to clear, but the temp will struggle to get out of the mid 30's,
so dress warmly. Thereafter, we will see another warmup by early next week with our next
threat for precipitation coming sometime on Tuesday. There are signs that a blocking
pattern will try to setup and keep the storm track farther south, but I've seen the models
forecast this many times already with the blocking going by the wayside. Regardless, get
ready for the big temperature swing tonight and check back early next week in regards to
any wintry weather which may be headed our way.
