Short term...(this evening through tuesday)
issued at 422 PM CDT Monday Jul 6 2015

The short term concern is the extent of smoke/haze into the region
and any fog threat in the east.

Dry surge dropping in behind departing front. Thicker smoke mixed
out over the northwest County Warning Area this afternoon...while spreading rapidly
in behind the departing front. Will mention some areas of smoke
through the afternoon. Latest model guidance was not available for a
smoke forecast so will leave out for tonight for now. Drier
dewpoints working over the area with northwest winds should preclude
significant fog formation. Maybe into west central Wisconsin late
tonight as winds diminish further and moist ground.

Mostly sunny and cool day expected for Tuesday with high pressure
dominating the area.

Long term...(tuesday night through monday)
issued at 422 PM CDT Monday Jul 6 2015

The remainder of the week will be benign...as broad surface high
pressure dominates the region and middle/upper forcing remains
displaced well out of the area. More active weather will arrive
for the upcoming weekend...including the return of warm and humid
air.

In the meantime...dry weather is expected to persist through the
next few days...along with cooler than normal temperatures.
Unfortunately it appears there will be another round of smoke
moving in on Tuesday evening and Wednesday. Highs will gradually
moderate from values in the middle 70s on Wednesday...to upper 70s to
lower 80s on Friday.

On Friday night into Saturday there has been consistency and
agreement amongst the models that the a warm front will lift into
the area. This will be our next decent opportunity for showers and
thunderstorms...and also a shot at highs nearing 90 degrees given
850 mb temperatures around +25c. Cloud cover may hinder that however...so
have stuck with forecast highs in the middle to upper 80s. This
boundary looks to stall near the area through the weekend...which
would mean occasional bouts of precipitation.

Aviation...(for the 18z tafs through 18z Tuesday afternoon)
issued at 1230 PM CDT Monday Jul 6 2015

Cold front exiting into Wisconsin this afternoon. IFR ceilings/visibilities
and rain showers continue to affect the area...mainly along the a cold
front/fgen region. This shifts east early will end through 00z
Tuesday. Farther west...MVFR ceilings shifting east...with gradual
clearing. Haze/fu another issue as it has been blown south over
western areas. Visible satellite shows smoke is advancing
south...and may clear out dissipate over the west late. Will have
to monitor model trends in the smoke forecast. Otherwise...looks
like fog will not be a major issue overnight as drier air moves
in. Could see some into west central Wisconsin late. Winds north-northwest
an gusty with frontal passage...through the afternoon. Should diminish after
01z Monday. Expect VFR Tuesday.

Kmsp...rain showers should end through 20z-21z with improving
ceilings and gradual clearing through 01z Tuesday. May see a smoke
issue into the evening but will leave 6sm haze for now. Gusty
north/northwest winds...diminishing this evening. VFR overnight
and Tuesday with north wind.

/Outlook for kmsp/

Tuesday night...VFR. Winds north-northwest 5kts.
Wednesday...VFR. Winds S 5-10 kts.
Thursday...VFR. Winds S 5-10 kts.
