Area Forecast Discussion
National Weather Service La Crosse WI
630 PM CDT Tue Jun 8 2021

.SHORT TERM...(Tonight through Thursday)
Issued at 205 PM CDT Tue Jun 8 2021

Frontal boundary/outflow from morning MCS hovering across central
MN/northern WI while Closed low was still pinwheeling across
MO/western IL. These two features will be the focus for
shower/thunderstorm chances remainder of this afternoon into this
evening. Mid-level stretching deformation from that closed low could
swing a few showers/storms in across southern forecast area (south
of I-90) while that boundary up north acts as a focus for some
convection on our northern fringes. Shear is rather weak, so
expecting sub-severe airmass/pulse type storms at this point with
heavy downpours given precipitable water values around 1.5 inches.
Otherwise, another anomalously warm and humid day with temperatures
at 2 pm in the mid-80s to lower 90s. Dew points were hovering in the
60s to near 70.

Expecting any convection to simmer down later this evening with
sunset/loss of surface heating. Look for overnight lows in the mid-
upper 60s.

Heat continues through Thursday with highs again in the mid-
80s/lower 90s. Could see afternoon shower/thunder chances as well
but again expecting these storms to be the airmass/sub-severe type
with localized heavy rainfall.

.LONG TERM...(Friday through Monday)
Issued at 205 PM CDT Tue Jun 8 2021

Some relief from the anomalous heat comes Friday night as a cold
front pushes through the region and upper level pattern transitions
to more of a northwesterly flow through the weekend. Shower/storm
chances continue into Saturday but then drier air moves in with the
northwest flow Sunday through Tuesday. Right now, looks like highs
Friday will be in the mid-80s/lower 90s pre-frontal, cooling into
the upper 70s to mid-80s Saturday through Tuesday along with dew
points drying into the upper 40s to mid 50s.
