Area Forecast Discussion
National Weather Service La Crosse WI
508 AM CDT Fri Apr 19 2019

.SHORT TERM...(Today and tonight)
Issued at 313 AM CDT Fri Apr 19 2019

At 3 AM, the cirrostratus shield associated with a low pressure
area over Tennessee had almost cleared the forecast area. This has
allowed good viewing of the full pink moon. The April full moon is
called this due to the wild ground phlox which produces pink
flowers and it is one of the first spring flowers. Temperatures
early this morning were in the lower and mid-30s north of I-94,
and ranged from the upper 30s to mid 40s elsewhere.

A ridge of high pressure will provide clear skies across the the
region for today and tonight. High temperatures this afternoon
will range from the upper 50s to mid 60s. Low temperatures on
Saturday morning will be in the 30s.

.LONG TERM...(Saturday through Thursday)
Issued at 313 AM CDT Fri Apr 19 2019

On Sunday, a Canadian cold front will approach the area from the
northwest. Southwest winds ahead of this from will allow 925 mb
temperatures to warm into the 20 to 21C range and 850 mb
temperatures will warm into the 13.5 to 15C range. These
temperatures are 1.5 to 2C standard deviations above normal in
NAEFS. Mixing these temperatures down to the surface results in
high temperatures ranging from the mid 60s to mid 70s north of
I-94 and near 80F elsewhere. This would make this Easter among the
10 warmest. More on these Easters can be found in the Climate
section below.

From late Sunday afternoon into Sunday night, this cold front will
slowly move southeast across the area. Capping near 700 mb ahead
of this front will initially limit the development of showers and
storms. By the time, storms do develop the instability will be
rapidly waning. This will likely prohibit the develop of severe
storms.

From Monday into Monday night, a low pressure system will move
northeast along the front which will be just south of our forecast
area. This will keep the showers and isolated thunderstorms going
across the area.
