Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
944 PM CDT Tue Jun 5 2018

.UPDATE...
Issued at 944 PM CDT Tue Jun 5 2018

Updated to include 06Z aviation discussion below.

.SHORT TERM...(This evening through Wednesday)
Issued at 331 PM CDT Tue Jun 5 2018

Dry conditions are anticipated to continue into the evening with
temperatures beginning to cool from daytime highs in the mid 70s
in West Central WI to 90s in Southwestern MN. Meanwhile, convection
forced by a shortwave trough and surface boundary over the
Dakotas is expected to evolve into a MCS and progress eastward to
the MN border near midnight. High resolution models are in decent
agreement with the propagation speed and direction with the MCS
continuing east-southeastward through Central MN.

The best chance for severe weather will be in West Central MN where
the MCS will likely still be organized and there is the most
MLCAPE near 2000 J/kg through 9Z. While there will be
stabilization in the boundary layer with increasing CIN through
the overnight hours, there is still potential for elevated
convective activity with severe wind and hail in East Central and
South Central MN. A 25-30 kt low- level jet will help enhance
moisture and shear with bulk shear values expected to remain near
35-45 kts overnight. The convective activity will likely become
less organized near sunrise but thunderstorm activity is expected
to continue into West Central WI and Southeastern MN.

Cloud cover over Southern MN due to the morning convection
decreases the chances for re-development of strong to severe
thunderstorms Wednesday afternoon. There is still 20-30 percent
Pops in the forecast as there is some uncertainty with the
evolution of the MCS and surface boundary. Recent model trends
indicate that convection will most likely fire along and south of
the MN/IA border Wednesday afternoon and leave the majority of the
CWA dry.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 331 PM CDT Tue Jun 5 2018

High pressure will allow for mostly dry conditions on Thursday,
however the GFS indicates a resurgence of the surface boundary
that may bring chances for precipitation to Southern MN Thursday
afternoon. Otherwise, the next chance for convective activity will
be Friday into Saturday with another shortwave trough. Sunday and
Monday are trending to be dry with upper-level ridging and surface
high pressure. Another upper-level trough is expected to bring
better precipitation chances late Monday into Tuesday. Otherwise,
the long-term looks mild with highs reaching the upper 70s to mid
80s each day.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 944 PM CDT Tue Jun 5 2018

Convection is well underway in western South Dakota, and is
starting to get going in North Dakota. Would expect the HRRR and
HopWRF to get a reasonable handle on things with the 03Z and 06Z
runs, and output from earlier runs still looks fairly reasonable.
So, at this point kept close to the going forecasts, which bring
things across the CWA from around 07Z through 15Z or so. Once
things get closer the timing, ceilings, and visibilities should be
able to be pinned down a bit better, but overall trends looks
similar to previous expectations.

KMSP...Main uncertainty is with what the eventual ceilings and
visibilities will be, which will depend on exactly where the
strongest remaining portion of the MCSs track. Timing could also
differ from +/- 2 hours from current estimate.

/OUTLOOK FOR KMSP/
Thursday...VFR. East wind around 5 kt.
Thursday night...MVFR possible with a chance of showers and
thunderstorms. Southeast wind 5 to 15 kt.
Friday...VFR. Southeast wind 5 to 10 kt.
Friday night...MVFR possible late with a chance of showers and
thunderstorms. Southeast wind around 10 kt.
Saturday...MVFR possible with a chance of showers and
thunderstorms. Southeast wind 5 to 10 kt becoming east.
