Area Forecast Discussion

1157 PM CST Wed Jan 17 2018

.SHORT TERM...(This evening through Thursday)
Issued at 325 PM CST Wed Jan 17 2018

Even with full sun and southwest winds, the temperatures are
struggling to warm up this afternoon. A few locations have managed
to get to freezing, but they are where there is little to no snow.

There is warm advection through the night and into Thursday. The
problem is that the surface winds are light. Temperatures will be
warmer, but may not reach the potential since the winds are light.
The snow will keep temperatures for the northeast part of the
forecast area a little cooler since it will take time to melt the
snow. Did lower temperatures over the snow pack a little bit, but
will have to see if we need to lower them some more.

.LONG TERM...(Thursday night through Wednesday)
Issued at 325 PM CST Wed Jan 17 2018

Warm advection will continue into Friday and Friday will be the
warmest day of the week. By then, there will be little to no snow
left. The winds at the surface continue to be light which is one
thing that could limit the warming.

Friday night there will be a cold front that moves through the area
and on Saturday temperatures will be a little cooler again, but
still not as cold as currently. Saturday night there will be an
upper level low that will be affecting the area through Monday. This
is a little slower than in previous runs. The forecast area remains
dry for Saturday night, with precipitation moving into the area on
Sunday and continuing into Monday. The models continue to have some
differences. The most notable with the latest runs is that the GFS
is faster than the ECMWF and Canadian. There are a few differences
in track besides. The precipitation should be mostly snow, but since
the track is a little further north than yesterday, there could be a
little more rain since the temperatures could warm a little more
during the day on Sunday. A few things that are more certain are
there will be precipitation and breezy conditions. Some that are not
as certain are precipitation amounts and type. Timing is a little
bit of a trick with model timing off just a little.

Since the system is a little slower than yesterday, there will
continue to be some snow for parts of the area on Monday. Skies
should start to clear out Monday night. Temperatures will be back
to cooler temperatures for Tuesday and Wednesday, but should still
be near normal for this time of year.
