.SHORT TERM...(This evening through Friday night)
Issued at 226 PM CDT Thu Jul 15 2021

Decreasing impacts are expected tonight as southwesterly winds
increase and help scour out the low-level smoke across eastern ND
and west central MN. A few weak cells may develop west of the
valley this afternoon but will be short-lived and erode after sunset.

High pressure now over the top of Lake Superior is resulting in
increasing return flow into central ND. The increase in WAA is
resulting in widely isold showers/possible a clap of thunder from
the upper James Valley into the northern Red River Valley, where
MLCAPE values are around 500 to 750 J/Kg. Shear values continue to
remain nil so any cells that develop will be rather slow moving
and short lived. More likely to see some spits of rain with this
activity, although some small hail with the strongest storms is
possible.

The SW winds are improving visibilities across eastern ND and smoke
smell is not as noticeable, however some reports or irritated eyes
remain. Will keep FU in on the east side of the river where winds
will be lighter and persist through mid-morning Friday. South winds
increase more in velocity tomorrow, resulting in highs in the upper
80s and lower 90s. There is potential for elevated smoke from fires
over the PAC NW to move into eastern ND late in the period, which
could impact afternoon highs. This episode should not be as
noticeable at the surface. Overall, a dry and breezy next couple of
days as a hotter airmass returns to the area.

.LONG TERM...(Saturday through Thursday)
Issued at 226 PM CDT Thu Jul 15 2021

Overall dry and warm conditions are expected across the region in
the extended time frame. Ensemble guidance brings the strong upper
ridge to the area this weekend and through the first part of the
week with the heat wave having a high confidence of occurrence.
Short term impacts will primarily be tied to above normal summer
temperatures with highs in the mid to upper 90s most likely with
some guidance suggesting triple digits are possible on the warmest
days of Tuesday and Wednesday when the thermal ridge axis settles
over the area. Long term impacts would be to enhance the ongoing
drought conditions and deteriorating crop conditions. As the upper
ridge weakens, weak short wave activity and weak surface wind shifts
or boundaries will eventually bring the chance for thunderstorms by
Tuesday night or Wednesday to the northern half of the area. This
will bring cooler temps however still above normal temps to the
area.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1235 PM CDT Thu Jul 15 2021

Increasing SW winds will help improve vsbys related to smoke for
the remainder of the afternoon. Otherwise, mostly clear skies with
exception of TVF/BJI seeing remnants of earlier convective
activity...those clouds should thin out/move east by end of first
six hour period.
