Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
1026 PM CDT Fri Jun 28 2019
.UPDATE...For 06Z Aviation discussion below
&&
.SHORT TERM...(This evening through Saturday night)
Issued at 258 PM CDT Fri Jun 28 2019
Two primary concerns are temps/dewps on Saturday as the weekend
heatwave cranks into gear, for which we have issued an excessive
heat watch for the Twin Cities, with a heat advisory for Saturday
extending from the west and south of the Twin Cities toward
southwest MN. Other main concern is then convective trends going
into Saturday night.
The stationary boundary this afternoon is laid out down near the
US-14 corridor in southern MN. SPC meso analysis shows 3k-5k j/kg
of mlCAPE along this boundary, but we're not expecting us to use
any of it. Cloud field on satellite is stable and incoming EML
looks to keep a lid on things. To get convection we would need
some form of forcing, but a remnant MCV from storms over ND this
morning will track across northern MN, to the north of the
instability gradient and we have divergent flow at h85, with the
LLJ branching off into two segments down in IA. One going from
southern IA toward Lake Huron and the other from Omaha up to
northwest ND. This leaves us void of forcing and capped, hence a
dry forecast for tonight.
For Saturday, we'll see h5 heights build to in excess of 594dm
over southwest MN, with a stout warm nose developing at about
825mb that will keep us capped. We may again have to deal with
some fog stratus Saturday morning, but we'll be starting off
tonight warmer than we did last night, so don't think fog/stratus
will be as widespread as what we saw this morning. We continued to
forecast highs in the low to mid 90s in MN and upper 80s to
around 90 in western WI.
Precip potential Saturday is still a bit uncertain. What looks
certain is that we'll see storms develop in the afternoon across
the ND/Manitoba border region. After that, evolution is uncertain.
Best upper forcing in terms of the upper jet and nose of the LLJ
will head for northwest Ontario, but the h85-h3 thickness pattern
and instability gradient would say this active should turn
southeast toward central MN through the night. There's little
agreement in the CAMs with how things will evolve Saturday night,
so have a forecast sounding similar to the previous one with
chance pops showing up in central MN after midnight. Given we'll
have MUCAPE in excess of 3000 j/kg with bulk shear of 30-40 kts,
there will certainly be a severe threat if we see anything work
into central MN.
.LONG TERM...(Sunday through Friday)
Issued at 258 PM CDT Fri Jun 28 2019
The extended period is becoming more unsettled in terms of active
late afternoon, and evening thunderstorms. Plus, periods of very
heavy rainfall leading to flooding problems, and severe potential.
The EC/GFS/GEM all support the upper ridge breaking down late
Saturday night and into Sunday as a strong short wave moves along
the Canadian border. Sunday's weather looks more complicated as
to whether a complex of storms that is expected to move southward
into central Minnesota Sunday morning develops more cloud cover,
and an increasing chance of precipitation in southern Minnesota
during the day. This could keep heat index values lower (WBGT
lower than expected), but at the same time, a much better chance
of precipitation by the afternoon. Current forecast has highs in
the 90s in southern Minnesota, and west central Wisconsin. I won't
deviate too much from this outlook, but these temperatures and
associated humidity levels will be dependent on the aforementioned
thunderstorms in northern Minnesota moving southward during the
day. Otherwise, the upper ridge will become centered across the
Mid- Mississippi River Valley region past Sunday, and through at
least the middle of next week. Our region will be on the northern
periphery of this ridge which means a fast west to east flow
aloft. Near the surface, the frontal boundary will likely stall
near the region, which will set the stage for an active weather
pattern along and north of this boundary. The low level flow next
week (southerly) will keep this boundary from dropping too far
south and allow for the very moist and unstable conditions to
linger across the Upper Midwest.
This basically means that all weather scenarios, in terms of heavy
rainfall, flooding, heat, and severe weather parameters, are
possible. The one parameter that looks to be the most concerning is
heavy rainfall and flooding. This is due to precipitable water
values of 150-200% above normal for this time of year. These values
mean that any precipitation that develops will be very efficient
with high rainfall rates. I wouldn't be surprised to see a
widespread area of 2 to 4 inches from Sunday through next Wednesday,
with locally higher amounts.
Another element that needs to be addressed is the possibility of bow
echoes/derecho's developing in this type of environment. A strong
west to east flow aloft in combination of a strong instability
gradient could lead to this type of scenario.
Past Wednesday/Thursday of next week, the EC continues to support
the upper ridge holding, while the GFS supports more northwest
flow developing aloft. If the GFS is correct, the end of next
week will be drier and cooler, while the EC supports the continued
muggy and wet pattern.

Issued at 1026 PM CDT Fri Jun 28 2019
The threat for stratus/fog development overnight is still the main
concern this TAF period, given the elevated low level moisture in
place. The most susceptible area still appears to be from the MN
River valley (near KRWF) south and east toward KMKT and KEAU,
where MVFR conditions have been included during the early morning
hours. Kept a few-sct mention at other sites. Should see any
reductions due to BR/stratus improve by late morning, with VFR
expected after that through the remainder of the period.
KMSP...Still favor a few-sct stratus mention with 5-6SM BR.
/OUTLOOK FOR KMSP/
Sun...VFR. Chc TSRA late. Winds SW 5-10 kts.
