.SHORT TERM...(This evening through Saturday night)
Issued at 308 PM CDT Fri May 31 2019

Temperatures this afternoon continue to rise slowly and range from
the mid 80s, to lower 90s at Cambridge, Red Wing, and portions of
west central MN. With another 2 or so hours of heating, several
more sites should eclipse 90 before all is said and done.

CU is finally beginning to develop across northern WI stretching
west to central MN along the surface cold front. A few showers
have also recently developed within the most impressive CU.
Additional showers and eventually thunderstorms will develop along
the front during the evening. Little forcing south of the front
should keep things dry, so reduced PoPs for the evening hours
across southern MN. While severe weather is generally not expected
with this activity, a few storms may produce gusty winds and one
or two may produce damaging winds.

Northerly flow will bring cooler temperatures Saturday with highs
in the upper 60s to mid 70s.

.LONG TERM...(Sunday through Friday)
Issued at 308 PM CDT Fri May 31 2019

The long term period will be relatively quiet, with only one decent
shot of precipitation and temperatures starting cooler than normal
Sunday, but warming early next week and highs remaining near to
slightly above normal for early June.

Sunday through Monday...cool high pressure from Canada will be in
place across the Upper Midwest Sunday morning. An upper level low
over the northern Great Lakes will likely lead to afternoon showers
to our northeast, but for most of southern MN and western WI, sunny
skies with highs around 70 degrees can be expected. With the dry
airmass in place, lowered dew points down to about the 10th
percentile of all the model guidance given deep mixing expected with
this airmass. So, dew point depressions around 40 degrees are
expected by Sunday afternoon. Thankfully, winds will remain
relatively light through the day, under 10 MPH.  Southerly flow
begins to develop across western MN and expand eastward Sunday night
as the surface high shifts southeast of the local area. Warm air
advection with the southerly flow developing will lead to warmer
temperatures come Monday. Another quiet day on Monday with highs in
the mid to upper 70s and mostly sunny skies.

Tuesday through Wednesday...continued warm and moisture advection is
in store for Tuesday along with a developing upper level shortwave
which looks to ride the upper ridge eastward across the Dakotas
through Minnesota. There are still timing differences to sort out
with this activity, but severe weather is not out of the question if
if dyanmics and the cold front associated with the surface low
across southern Canada move through our area during peak the
afternoon and evening, which would result in forcing aligning best
with instability. Due to timing differences and being several days
away, went with blended guidance for PoPs for this period. The cold
front itself will likely clear MN and wester WI by Wednesday
morning, which will be followed by dry high pressure and more
pleasant weather. Sunny skies with highs from 75 to 80 can be
expected again for Wednesday.

For the end of next week, the main jet lifts farther north into
Canada and we will likely see continued dry weather with highs
remaining the 75 to 80 degree range.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 110 PM CDT Fri May 31 2019

VFR through the period outside of any thunderstorms. Scattered
storms are expected to develop early this evening over central MN
into northwest WI and sag south tonight.

KMSP...Pushed back the timing of the thunderstorm activity to
mid-late evening, but there could be an isolated storm or two
across the region late this afternoon. The smoke seems to have
hampered CU development so far this afternoon, so this is looking
less and less likely until the cold front begins to approach
later.

/OUTLOOK FOR KMSP/
Sun...VFR. Wind NW 5-10 kts.
Mon...VFR. Wind SE 5-10 kts.
Tue...Chance TSRA/MVFR. Wind S 5-10 kts.
