Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
216 PM CDT Tue Jul 5 2022
.DISCUSSION...(This evening through Tuesday)
Issued at 205 PM CDT Tue Jul 5 2022
* KEY MESSAGES: (optional)
- Severe thunderstorms possible late this afternoon and early evening
near the I-90 corridor. Damaging wind gusts and large hail would be
the primary threats.
- A bit cooler the next couple of days, otherwise mainly above normal
temperatures through the period.
- Mainly dry for the end of the week into the weekend, then
increasing precipitation chances for the end of the weekend into
next week.
Satellite imagery this afternoon shows scattered to broken cu across
most of the area, with some lingering stratus transition to cu
north of the metro area. Intense forward propagating MCS can be seen
on satellite and radar across eastern South Dakota. This system will
continue to move east-southeast through this evening along the
northern periphery of the instability axis (with MUCAPE values of
3000-5000 J/Kg). The northern portion of this feature may impact the
southern portion of the area, with additional convection likely
developing out ahead of it near the I-90 corridor by around 22Z.
Primary concerns will be damaging wind gusts and large hail, although
isolated tornadoes cannot be ruled out. The metro area is expected to
remain dry, although some stratiform precipition and embedded thunder
north of the MCS could make it up into the southern metro area during
the evening.
Instability will remain in place through Wednesday as a weak
shortwave trough moves around the periphery of the upper ridge. This
could bring some shower and thunderstorm activity across the area
from west to east Wednesday into Wednesday evening. The primary
baroclinic zone will be depressed southward by Thursday as stronger
subsidence works into our area, with surface high pressure centered
over Ontario building over us from late Thursday into early Saturday.
Return flow will setup by late Saturday, and precipitation chances
will start to increase from west to east Saturday night into Sunday,
with chance PoPs needed for much of the area into Monday. Somewhat
cooler and drier air then looks to build in from the north late
Monday into Tuesday.
&&
.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1218 PM CDT Tue Jul 5 2022
Warm and humid airmass will remain in place through the period. Fog
and stratus from overnight into this morning has mostly burned off,
leaving some diurnal cu in its wake. Focus is no on a forward
propagating MCS moving through South Dakota. This is expected to
move through far southwest Minnesota and northern Iowa later this
afternoon and this evening, but will need to keep an eye on it. Did
not include anything in the KRWF and KMKT TAFs at this point, but
could need some lower clouds and SHRA/TSRA should it move farther
north (or activity develop to its north). Otherwise, VFR conditions
are expected to persist through the period (other than anything that
could occur with low probability convection), with light north/east
winds.
KMSP...Only item of concern looks to be lower VFR/marginal MVFR
ceilings late tonight and Wednesday morning. However, given the
instability that is in place across the region, there remains the low
probability chance for thunderstorms tonight into Wednesday. The
probability (and confidence in guidance) is too low to include any
mention at this point.
/OUTLOOK FOR KMSP/
Wednesday night...Occasional MVFR expected, IFR possible. Light and
variable wind.
Thursday...MVFR/IFR possible early. Variable wind 5 kt or less.
Thursday night...VFR. Northeast wind 5 kt or less.
Friday...VFR. Northeast wind 5 to 10 kt becoming east.
Friday night...VFR. East wind 5 kt or less becoming southeast around
10 kt.
Saturday...VFR. Southeast wind 10 to 15 kt.
