.SHORT TERM...(This evening through Monday)
Issued at 424 PM CDT Sun Jun 17 2018

Subtle short wave has helped kick off storms from southwest MN
into east central MN and northwest WI. A cold front extended along
this area as well, and there is quite the temp and dew point
difference. Precipitable water values remain around two inches.
Winds aloft are not all that impressive, but the low level jet is
anticipated to strengthen by about 10-15 knots this evening per
several short term models. Front is projected to accrue more of an
ene-wsw orientation, and with storms continuing to develop to the
southwest, the concern is for storms to move across the same area
tonight. Several other factors are present as well, and some areas
could pick up several inches of rain. Thus issued a flash flood
watch in coordination with neighboring offices. Severe weather is
also a concern and while some storms have shown decent rotation
and updraft strength, there have not yet been any reports of
severe weather in our area.

Once the front moves through, abundant residual moisture and temps
dropping by 20-25 degrees should promote extensive cloud cover
later tonight and tomorrow morning.

.LONG TERM...(Monday night through Sunday)
Issued at 424 PM CDT Sun Jun 17 2018

With upper low over Hudson Bay and upper high centered over the
southeast, upper flow over MN/WI will mostly be zonal later
tomorrow, and then our area is affected by southwest flow from
the next upper low moving into the western states. Thus have
precip chances over most of the area through Tuesday night, though
probabilities will be on the low side. Western upper low will
slowly move east, and flow will become favorable for general lift
with any short waves, none of which appear to be very strong. Thus
have low chances for precip later Wednesday through the rest of
the week. Temperatures look seasonable for the week.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 713 PM CDT Sun Jun 17 2018

A cold front will move through the region overnight with northwest
winds and MVFR, possibly IFR ceilings after is passes. Ahead of
the front expect some showers and thunderstorms this evening along
with southwest winds. Ceilings should gradually improve on Monday,
with VFR conditions spreading from west to east Monday afternoon.

KMSP...
Winds should remain northerly, but could see a few changes in wind
direction with the outflow boundaries from the evening shower and
thunderstorms. Precip chances will taper off after sunset, but
should see MVFR and possibly IFR conditions overnight. Expect VFR
conditions to return Monday afternoon as winds become more
northeasterly.

/OUTLOOK FOR KMSP/
Tue...VFR. Wind NE 10 kts.
Wed...VFR. Wind ENE 10G15 kts.
Thu...VFR. Wind ESE 10 kts.
