Updated to include 00z aviation discussion below.

.SHORT TERM...(This evening through Monday)
Issued at 215 PM CDT Sun Apr 22 2018

Little weather in short term. Some high clouds will move across
the state overnight associated with weak trough axis associated
with the exiting cutoff circulation to the south. Much of the
moisture has exited to the south and is thinning. With the light
winds and still melting snow cover in south central MN we could
see some patchy fog again late there. Didnt mention at this time
the SREF probs are lower than yesterday and we were only able to
get a few 3-5sm on AWOS sites 11z-13z. Temepratures will drop off
through the 30s and much of the area should remain above freezing
overnight.

The surface ridge remains in place again for Monday with the next
cold front moving into northern MN. We expect plenty of sunshine
again with temperatures warming the 60s most areas.

.LONG TERM...(Monday night through Sunday)
Issued at 215 PM CDT Sun Apr 22 2018

The deterministic models continue to indicate split flow
associated with the upper flow pattern associated with Tuesday
front. Much of the energy is shunted to the east in the northern
stream flow with the cutoff circulation dropping well west of MN
across South Dakota and Nebraska into Wednesday. We should be able
to work some light rain into far western MN before waning as it
drops southeast with the front across southern MN. We retained
some small PoPs to the west and south for now.

The next front still looks to move through the area
Thursday/Thursday night. Somewhat cooler air follows this front
into Friday but the GFS is more progressive with its western CONUS
trough into the weekend. This brings higher heights aloft and
warmer air into the area for the weekend. We will trend warmer
with readings close to or slightly above average by next weekend.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 525 PM CDT Sun Apr 22 2018

Weak ridge axis aloft, oriented NE-SW from eastern Canada into
the Four Corners region, with exiting surface high pressure will
be the main features at play through tomorrow evening. The ridge
will keep a dry surface cold front off to the west, helping
maintain weak south to southwest winds tonight through tomorrow.
Only clouds look to be FEW-SCT high cirrus clouds drifting over
the area. Long story short, solid VFR conditions expected.

KMSP...No significant weather impacts expected.

/OUTLOOK FOR KMSP/
Tue...VFR. Slight chc -SHRA. Wind NE 5-15 kts.
Wed...VFR. Wind variable around 5 kts.
