.DISCUSSION...
Issued at 248 AM CDT Thu Jul 18 2024

...Synopsis...

Current satellite imagery showing high pressure over the area this
morning, with clouds to the west in Saskatchewan and Montana. This
weak high pressure over eastern North Dakota and northwestern
Minnesota will stick around until this evening, when a UL shortwave
on Friday will give us the first of many rain chances. Afterwards,
NW flow aloft will combine with daytime heating and give us rain
chances practically every day. Temperatures will increase into the
mid 80s for highs by beginning of next work week.

...Daily Precipitation Chances...

Starting this evening, with a weak upper level shortwave,
precipitation chances will increase into Friday morning.
Probabilities for receiving >0.25 inches in the area are less than
20%, due to very weak forcing. The environment is enough to get some
showers and thunderstorms though, but they will be reminiscent of
afternoon pop-up storms. With the weak shear and forcing, no severe
weather is anticipated currently. With northwest flow aloft being
ushered in behind this shortwave, chances will be slight every day
for showers and thunderstorms. QPF is not expected to be high with
these showers and thunderstorms.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1227 PM CDT Thu Jul 18 2024

VFR conditions through the TAF period, with brief MVFR ceilings
possible. Cumulus has continued to increase east of the Red
River Valley and has the potential to reach GFK, FAR, and TVF
this afternoon and evening. Ceilings are VFR, but may drop
briefly to MVFR at times. BJI will be under the cloud deck
through sunset. Otherwise, there is a slight chance for shower
and an isolated thunderstorm for eastern North Dakota end of the
TAF period, but confidence is on the low.
