...New AVIATION...

.SHORT TERM...
(Today through Tuesday) 
Issued at 951 PM CDT SUN JUN 15 2025

Activity across the area will continue to weaken through the early
night, with patchy fog potentially developing in areas across the
south that received rain through the evening. Monday, diurnally 
driven activity is expected again, increasing in coverage in the 
early afternoon through the early night. Instabilities will be 
2000-3000 J/kg with PW values near 1.8 inches. Shear and wind 
profile is weak across much of the area so would expect strong 
winds and small hail in the stronger thunderstorms and heavy rain 
in any thunderstorm. Slow moving or training storms may cause a
localized flooding threat, especially in areas that received high
rainfall totals in the past couple of days. 

A weak trough will bring an increase in mid and upper level winds
beginning Monday night through Tuesday. Instabilities will be
higher Tuesday afternoon, with low level winds increasing in 
strength from the southwest and PW values increasing to over 2.2 
inches. The coverage of thunderstorms Tuesday may be greater than 
the past couple of days, with the same threats as Monday 
afternoon. 

With the coverage of storms and plenty of cloud cover,
max temperatures each afternoon will be in the mid 80s to lower 
90s. However, the moisture will allow for soupy air and heat 
indices to reach the upper 90s in many places before any 
thunderstorm development. Once thunderstorms work through an area,
the heat indices and temperatures should be much lower.

.LONG TERM...
(Tuesday night through next Sunday)
Issued at 951 PM CDT SUN JUN 15 2025

Tuesday night through Wednesday night, the area will have 
southwesterly flow prevail with low level moisture and warm air over 
the area and a diurnal pattern with showers and thunderstorms 
developing each afternoon and weakening by the early night. Plenty 
of instability and weak shear will allow for storms to build and 
produce gusting winds and small hail. PW values are max for this 
time of year, so heavy rainfall totals will be possible in any 
storm, with localized flooding likely in any training storms. 

Tuesday night through Wednesday night, a low pressure will develop 
across the northern plains and move east. Models are a smidge more 
in agreement tonight than last night with the low passing just south 
of the Great Lakes, and swinging a boundary through the state 
Thursday. The timing of the boundary will allow for scattered 
activity through the morning, with thunderstorms again in the 
afternoon. The low should be far enough north though, that the best 
forcing will remain north of the area. Will not advertise threats 
much different than any other summer time diurnally developing 
convection at this point. This activity should weaken after sunset 
Thursday night. 

Friday, the boundary should stall over the southern half of the 
state. Northerly flow behind the boundary will keep lower moisture 
and instabilities over the northern half of the area, with the most 
likely coverage of afternoon thunderstorms over the southern areas. 
Depending on how far south the boundary makes it may depend on how 
much of the area can see convection. By Saturday, high pressure will 
build over the area. Though low level flow will be slow to return to 
a southerly direction thanks to the location in the high, there 
should be diurnally driven thunderstorms each day through the 
weekend.

Each day, there is plenty of moisture for heat indices to feel
like the upper 90s, especially in areas across the west and the
south. Behind the front on Friday through the end of the weekend,
heat indices may rise into the triple digits each afternoon.

.AVIATION...
(12Z TAFS)
Issued at 614 AM CDT MON JUN 16 2025

Variable cloudiness this morning will give way to increasing
clouds this afternoon and scattered to numerous showers and storms
generally after 20 to 21z. Convection will remain through 3 to 5z
and then we will likely see the low clouds develop again. 

NOTE: AMD LTD TO CLD VIS AND WIND has been added at MGM until 
further notice due to comms issues.

.FIRE WEATHER...

MinRH values are forecast to remain above 50 percent for the next
several days as very moist air mass remains in place over the 
region. Daily rain chances will remain elevated as well. 20 ft 
winds will be from the south to southwest at 5 to 10 mph through 
at least Wednesday, transitioning to a more westerly direction by
Thursday.
