.DISCUSSION...
Issued at 223 AM CDT Thu Mar 14 2024

A palpable state of envy is an appropriate response as we look at
regional radar and satellite this morning, with a broad area of rain
falling over southern Iowa and northern Missouri. There are a few
showers in southern Minnesota, however our surface dew points
started low enough such that much of it has remained virga thus far,
with further showers only expected along I-90 today. The broad
forcing is evident ahead of a longwave trough stretching over the
western half of the CONUS, with a developing surface low tracking
along the area of weak CVA on the southeastern side. Most of our
area will once again end up skunked as high resolution guidance has
the low tracking to our southeast, resulting in only a few showers
along I-90 today with the majority of the MPX CWA remaining dry. As
the system transitions towards the Great Lakes by late tonight into
early Friday, we will end up within the left entrance region of the
upper level jet, ensuring continued subsidence and dry conditions. A
broad area of high pressure will then develop over the eastern Rocky
Mountains later tomorrow, with skies briefly clearing before pattern
shift will bring about colder temperatures this weekend.

Another surface low develops over central Canada and quickly slides
eastwards to the south of Hudson Bay by Saturday afternoon, dragging
a cold front through the region which will be dry due to low
available moisture, with the main consequence being increasing winds
out of the west to northwest. These winds will begin to bring colder
air to the region, with temperatures dropping into the 20s for low
and mid to upper 30s for highs by Sunday. High pressure looks to
lock this cold air in place through most of Monday and Tuesday
before we see another non-precipitating system slide across the area
giving us yet another airmass change with no moisture. The 7 day
forecast looks remarkably dry especially should we see nothing
today, with long range ensemble guidance showing hints of a trend
towards a more active pattern by the last week of the month.
However, given how the rest of 2024 has gone thus far, I`m not
holding my breath until I see the radar echoes bearing down on us
right as it is happening.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1151 AM CDT Thu Mar 14 2024

VFR conditions for most of this period with some MVFR possible
across western and central Minnesota sites Friday morning.
Overall the rain has remained to the south of the terminals
today with little more than OVC sky for us. These clouds will
move out with the larger system later today with a clear or
mostly clear (with some high clouds) overnight. Winds today will
be from the north to northeast and occasionally gusting up
around 20 knots. Winds will become lighter tonight and shift to
the northwest.

KMSP... VFR through the day with winds as the main impact today.
North to northeast winds continue with gusts up to around 20
knots this afternoon. During periods with a more northeasterly
wind this could cause some crosswind issues with the parallels.
Winds will shift to a more consistent northerly direction this
evening before going to the northwest by tomorrow morning.

/OUTLOOK FOR KMSP/
SAT...VFR. Wind NW 15-25G35-40kts.
SUN...VFR. Wind NW 15-20G25-35kts.
MON...VFR. Wind NW 10-15kts.
