  outdoors or those susceptible to heat illnesses, such as 
  children and the elderly. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Heat Advisory means that a period of hot temperatures is

Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
1257 PM CDT Sun May 27 2018

.UPDATE...

&&

.SHORT TERM...(Today and tonight)
Issued at 358 AM CDT Sun May 27 2018

The main forecast concern in the short term is heat. H85 temps warm
+2C today, and we will have a more favorable wind direction for
warming (southerly), so should see temps moderate a few degrees from
Saturday's highs. Expect readings to range from the low/mid 90s
north of I-94 to the mid and upper 90s south of I-94. Dewpoints will
mix out into the mid 50s to lower 60s. Heat indices are therefore
technically borderline for warranting a heat advisory (100 degrees
outside of the Twin Cities), but given 1) it's the first heat wave
of the season 2) it's occurring during a peak time for outdoor
activities and 3) winds over much of central and south central MN
will be light enough to provide insufficient cooling relief, have
issued an advisory for much of central and southern MN.

The secondary concern today is the potential for showers and
thunderstorms over the eastern Dakotas to work into west central MN
this morning. Have include a short window of 30 POPS generally north
and west of a Madison to Little Falls line.  The activity should
wane by late morning, with plenty of time for temps to recover once
clearing commences.

Tonight a weak boundary sets up over northern/central MN as weak
shortwaves top the mid/upper ridge and move along the International
border. We could see associated showers and thunderstorms as far
south as I-94. Have include 20-30 POPS to cover the potential for
scattered activity.

.LONG TERM...(Monday through Saturday)
Issued at 358 AM CDT Sun May 27 2018

The upper-level ridge over the Great Plains and the trough over the
Great Basin progress eastward on Memorial Day. While we will remain
mostly under the ridging, a surface frontal boundary and subtle
shortwave brings slight chances for showers and thunderstorms Monday
evening. At this time, the best storm chances look to be in Northern
and Central MN. There will likely be ample instability with both the
NAM and GFS indicating MUCAPE values of 2000+ J/kg. If thunderstorms
do develop, near 20-25 kts of bulk shear may allow for some
organized thunderstorms capable of strong winds and hail.

Another concern for Memorial Day is the heat. Southerly flow continues
and skies look to be mostly sunny with the exception of afternoon
cumulus and the convection late in the day. This will allow
mixing to near 750 mb as evident in NAM and GFS soundings. This
will allow temperatures to warm into the mid to upper 90s along
and south of I-94 and lower 90s to the north. Dewpoints are
expected to be in the lower 60s with widespread heat indices in
the mid to upper 90s with the highest approaching 100 degrees in
the TC metro.

Tuesday will still be unseasonably warm with highs in the upper 80s
to lower 90s. Thunderstorm potential increases Tuesday afternoon and
evening with increasing cyclonic vorticity advection ahead of the
approaching upper-level trough and surface low pressure along the
CA/US border and north-south oriented frontal boundary. The
unsettled weather pattern is expected to continue through Wednesday
night before the frontal boundary and shortwave trough exit to the
east. Weak ridging looks to commence Thursday while the upper-level
trough to the east looks to "absorb" the circulation from the
remnants of subtropical Storm Alberto.

Dry weather is forecast through early Saturday, however the chance
for embedded shortwaves on the northern edge of the ridge will have
to be monitored. Otherwise, the next best chance for precip looks to
be late Saturday into Sunday with a trough approaching from the
Northwest CONUS. High temperatures Wednesday through Friday are
forecast to be in the lower to mid 80s. Then, temperatures Saturday
and Sunday will likely be even cooler in the in the 70s to near 80
degrees as they will be influenced with the precip and cloud cover
associated with the trough.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1257 PM CDT Sun May 27 2018

VFR conditions will prevail throughout the period with an area of
decaying thunderstorms near STC further continuing to weaken.
Winds will be northwesterly for a few hours at STC,MSP,RNH, & EAU
in the early afternoon as the outflow boundary from these storms
moves east. Otherwise, winds are expected to be southeasterly this
afternoon, become southerly overnight, and generally out of the
west through Monday morning. High clouds will diminish somewhat
this afternoon but will increase in coverage again tomorrow
morning.

KMSP...Tricky winds this afternoon with the outflow boundary over
the area. Expected to remain northwesterly to northerly through
early afternoon, and then gradually become more southeasterly.
Thunderstorm chances increase towards 00Z Monday but since this is
at the very end of of the TAF period, will keep any mention of
precip to the AFD for now.

/OUTLOOK FOR KMSP/
TUE...Mainly VFR. Chc -SHRA/-TSRA. Wind S 10G20 kts.
WED...Mainly VFR. Chc -SHRA/-TSRA. Wind S 10G20 kts.
THU...VFR. Slgt Chc -SHRA/-TSRA. Wind WNW 10 kts.
