.DISCUSSION...
Issued at 315 PM CDT Tue Jun 25 2024

For most of us this afternoon and evening, the weather is expected
to remain calm and quiet with temperatures cooling into the
upper 50s and low 60s tonight. Currently, a surface boundary is
acting as the dividing line for scattered cloud cover across
southern MN whereas clear skies prevail elsewhere. A subtle
shortwave continues to move in from Alberta tonight into the
pre-dawn hours which will interact with this boundary. Scattered
rain showers are possible mainly across western MN with
expected QPF ranging to less than a tenth of an inch.

By Wednesday, upper-level ridging begins to build in from our west.
Aside form patchy afternoon clouds tomorrow afternoon, Wednesday
looks to be a beautiful day and not as humid. NW`ly flow will aid in
reducing high temperatures to the low to mid 70s, with dew points in
the 50s. Thursday looks to be a replica of Wednesday`s
temperature forecast however southerly flow returns in the mid-
levels. Dew points will begin to creep back to near 60 degrees
with increasing cloud cover from the southwest throughout the
day. A shortwave across the intermountain west encroaches on
the Dakotas and is progged to track across the international
border Thursday night into Friday. Central MN continues to be
saddled between two >1" QPF maximas to our north along the Int`l
border and south of the MN/IA border. Moisture content
associated with this system brings PWATs as high as 1.8" which
does introduce the potential for some heavy rainfall. A few of
the forecast soundings do hint at some meager instability Friday
afternoon but severe weather is not anticipated. Expected
rainfall amounts will range between a quarter to a half inch
with this system. Although given the progressive nature of this
system, training rainfall is not expected which does help
rivers continue to recover from flooding.

This weekend looks to be ship shape with mostly clear to partly
cloudy skies and temperatures in the upper 60s to low 70s. Early
next week remains our next period to watch as troughing to our
NW become negatively tilted. Stronger convection is possible
along with another opportunity for heavier rainfall. As
mentioned in the previous discussion, the system doesn`t look to
linger around to pester any fourth of July activities.

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 548 PM CDT Tue Jun 25 2024

A band of light showers is possible across the southern half of
MN from about 9-12Z Wednesday morning. For the remainder of the
morning, cigs look to fall to near 3500 feet before a cumulus
field near 5000 feet develops by the early afternoon. Thus, it
appears likely that VFR will prevail the entire period. Westerly
winds will slow tonight and become northwesterly after a cold
frontal passage. Winds will increase to near 10 knots Wednesday
afternoon and become more northerly with time.

KMSP...Added some light showers from 9-13Z Wednesday morning but
impacts should be minimal. VFR expected the entire period.

/OUTLOOK FOR KMSP/
THU...VFR, MVFR/SHRA late. Wind S 5-10kts.
FRI...VFR/MVFR, chc -TSRA. Wind SE 10-15kts.
