Area Forecast Discussion...UPDATED
National Weather Service Twin Cities/Chanhassen MN
711 PM CDT WED JUN 8 2016

.SHORT TERM...(This evening through Thursday)
Issued at 420 PM CDT Wed Jun 8 2016

Ongoing showers and thunderstorms in western MN this afternoon are
slowly working eastward with time.  Strong theta-e advection across
that area is aiding in providing enough lift to tap into elevated
instability and produce scattered thunderstorm activity.  This area
will likely expand as a low level jet evident at 850mb increases
after dark.  Hence, increased pops across the board with likely pops
moving through.  With confidence increasing in the expansive
precipitation area later, upped QPF values to near 0.5", much needed
rain for many.  Thunderstorms are generally expected to be sub-
severe and remain elevated tonight.  We could see small hail in some
of the stronger cores, so that and lightning are the threats for
folks outside.

We could see fog form overnight across portions of the forecast
area, but at this time confidence in the extent and density is low
so left it out of the official forecast.

For tomorrow we see the pattern change continue with southwesterly
low level winds and the hot upper ridge beginning to build in.  Dew
points will be on the rise as well, so this will be the beginning of
a bit of a hot and muggy stretch to finish out the week and head
into this weekend.  Dew points will rise into the mid and upper 60s
by tomorrow afternoon, so it will feel quite a bit different outside
24 hours from now.

.LONG TERM...(Thursday night through Wednesday)
Issued at 420 PM CDT Wed Jun 8 2016

The ridge builds in across the Upper Mississippi River Valley
Thursday night into Friday and a warm front lifts north across the
area. South of the front, which should be most of southern MN and
west central WI, we expect upper 80s to mid 90s for highs to go
along with dewpoints that climb well into the 60s. We wouldn't
surprised to see a few locations hit 70 for a dewpoint. The
biggest question on Friday is just how far north does the warm
front set up, because along and north of this boundary, there will
be a chance for thunderstorms. At this time, this looks to be more
like northern MN during the day Friday, but the front should sag
southward during the evening and pull the CAPE/moisture gradient
south. If this happens, then most of the forecast is at risk to
see a cluster of showers and storms late in the day on Friday
along the instability gradient. We have added pops to the forecast
to account for this threat. The GFS/ECMWF are more consistent with
this thinking than they have been in previous runs. Saturday is
trending a bit warmer than the past couple runs and the break
down of the upper ridge still looks to take place Monday and
Tuesday and bring another 1-2 rounds of showers and storms.
Overall, the heat remains, but the threat for rain looks better
over the next few days than what we were previously thinking.

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 711 PM CDT Wed Jun 8 2016

A band of scattered thunderstorms from just south of KAXN to KRWF
and KMKT is slowly lifting north with a warm front early this
evening. Think they will begin to reach the vicinity of KMSP
around 02Z, KSTC around 03Z, KRNH around 04Z, and KEAU after
06-07Z. They should continue most of the night, gradually focusing
more into Wisconsin later tonight. Brief IFR conditions are
possible with any of the storms. Otherwise, expect VFR conditions
and light southeast winds.

KMSP...Best chance for TSRA will be from mid evening to the early
overnight, but they could linger beyond 08Z. A couple outflow
boundaries are lifting north into the southwestern metro area, and
winds may briefly turn south or southwest if they push past the
terminal.

/OUTLOOK FOR KMSP/
FRI...VFR. CHC TSRA late. Winds S 5-10 kts.
SAT...VFR. Winds NE 5 kts.
SUN...VFR. CHC TSRA late. Winds SE 5-10 kts.
