.PREV DISCUSSION... /Issued 353 PM CDT Sun Apr 15 2018/

DISCUSSION...

Still some lingering scattered cloud cover across far northeast
Oklahoma and northwest Arkansas on the backside of the large trough
that is working its way up towards the Great Lakes region this
afternoon. After a chilly morning with lows in the upper 20s and
lower 30s, afternoon high temperatures managed to top out in the
mid 40s to lower 50s across much of the forecast area.
Unfortunately, another cold morning is in store for the region
with surface high building in overnight. Clear skies tonight will
allow for good radiational cooling and temperatures are expected
to drop several degrees lower than temperatures did this morning.
A few of our low-lying cold spots could even see a few mid 20
degree temperatures.

After a cold start...Monday will turn into a fairly mild spring
day with temperatures warming into the 50s and 60s, and light
winds. On Tuesday, a warm front will translate northward through
the forecast area and with thermal ridge positioned across the
Southern Plains...temperatures will quickly warm into the 70s and
80s. However, deepening lee trough and increasing pressure
gradient will make for another windy day. Windy conditions will
continue behind Tuesday night`s cold frontal passage. Midlevels
will be significantly dry behind this front and with boundary
layer moisture lacking...could see fire weather concerns
Wednesday afternoon. Precipitation chances will remain north in
area of better forcing and moisture profile as the shortwave
trough moves through.

Precipitation chances will increase late in the week and through
much of the weekend as another Pacific trough closes off over the
Great Basin and then begins its eastward progression across the
Plains.
