Special Weather Statement, NWS Twin Cities, MN

Area Forecast Discussion...UPDATED
National Weather Service Twin Cities/Chanhassen MN
648 PM CDT Fri Jul 5 2019

.SHORT TERM...(This evening through Saturday night)
Issued at 257 PM CDT Fri Jul 5 2019

A very slow MCV over western Minnesota has been struggling to
make much eastward progress after the mid morning hours.
Widespread showers associated with it have been keeping western
MN wet for most of the day. The heaviest cores are nearest the low
center, where rainfall rates of a 1/2 to 1 inch/hr are occurring.
The showers will expand eastward slowly late this afternoon.
Cloud tops warmed and some decrease in the overcast late this
morning led to a fair amount of sun today across southern MN and
western WI. Therefore, we should see some cells build into
thunderstorms during the next couple hours. Given the slow
movement of the system as a whole, the cores aren't expected to
move much and if rainfall rates continue to increase with
strengthening convection then flash flooding will become a
concern. The area most at risk for this is currently developing
just south of Willmar, but should expand eastward to the Twin
Cities metro by this evening. Eventually the MCV will weaken this
evening and the loss of daytime instability should allow precip to
gradually weaken after sunset as it heads into WI. PoPs trend
downward after about 8 PM and most of the precip will be done by
midnight.

The forecast for Saturday still remains a bit uncertain with
regard to precip potential. For the last several days, guidance
has not handled these MCVs well at all and there will be another
one approaching from the west for Saturday. This MCV is currently
over southeastern MT. The overall consensus still appears to be a
gradual shearing of this feature for the next 24 hours. With high
pressure building to the north and a bit drier air in place, the
hand is tilted more toward a drier forecast than what has
transpired today. Couldn't remove PoPs tomorrow, but didn't have
much evidence to increase them either. Therefore, maintained a low
chance PoP, mostly across southern MN.

.LONG TERM...(Sunday through Friday)
Issued at 257 PM CDT Fri Jul 5 2019

Confidence in the extended period remains medium based on the mean
flow aloft from the models which provided a good scenario on the
best chance of precipitation Tuesday, and Tuesday night. Models have
some timing differences and strength of the short wave moving out of
the Rockies and into the Northern Plains, and Upper Midwest Tuesday,
and into Wednesday. Overall, fairly well wind shear, instability,
and moisture availability indicates a good swath of thunderstorms
will occur sometime Tuesday, and Tuesday night. However, any severe
weather is dependent on timing.

For Sunday, and Monday, an upper ridge will build across the region.
However, at the surface, return flow develops and may allow for
isolated storms during the typical afternoon/early evening time
frame where localized surface moisture convergence is noted.

After the main short wave moves across the region Wednesday, a
couple of days of mostly dry conditions should prevail. Models also
support an upper ridge building across the Rockies which will lead
to some concerns on ridge riders by the end of the extended period.
Overall, temperatures will be near normal for mid July with highs in
the 70s/80s, and lows in the 60s, to near 70.|
