10 FEB Short-range

Forecast updated 1:00pm EST - 10 Feb 2011

Meteorologists don't like to use the term "boring" to describe the weather, so we will
just say that the weather is simply not interesting in the short-range. The image below is
valid all day on Friday, February 11, 2011. Temperatures tomorrow will not be nearly as
cold as today, but much of the country will still be below normal. The region north of the
blue line will continue to remain well below freezing for yet another day. It will also be partly
to mostly cloudy during the day on Friday. The rest of the country, with the exception of
the coastal Northwest and Florida, will see mostly sunny skies.

Negative vorticity advection will trump any warm air advection across the midwest,
to keep it clear. As indicated, the long-range forecast includes a much welcomed
warm-up! A nice ridge should build across this frozen tundra called the US by the
end of this weekend.

For Lafayette, lows tonight will be around 5 degrees (above zero!). Highs tomorrow in the
mid-20s, and lows on Friday in the lower 20s. Similarly for Indianapolis, lows tonight
will be in the upper-single digits (above zero, too!), highs in the upper-20s to near 30,
and lows Friday night in the mid-to-lower 20s.
