Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 605 AM CDT Sun Aug 9 2020

UPDATE. For 12Z Aviation discussion below

SHORT TERM. (Today through Monday) Issued at 247 AM CDT Sun Aug 9 2020

The first concern in the short term is the wind-producing MCS over eastern South Dakota that is on our western doorstep. Damaging wind gusts are the greatest concern with this complex as it races east this morning, and also large hail given mid-level lapse rates of 8.5-9 C/km. Do expect a waning trend with eastward progression moving into a region of lower DCAPEs/MUCAPEs, as we're seeing with wind gusts more in the 45-50 mph range in southwestern Minnesota, but storms should be at least strong through 14Z.

We likely won't be out of the woods after this line moves through, however. Several of the Hi-res models, particularly the HRRR family, show redevelopment of strong storms over central/east central MN between 15Z and 18Z, expanding across west central Wisconsin during the early afternoon. This scenario seems very possible given the forcing the shortwave will supply in combination with plenty of instability and shear.

And yet a third round of convection will be possible this evening as thunderstorms develop along the front over the eastern Dakotas and race eastward across the area. Damaging wind and hail will again be the primary threats. Additionally, given the subsequent bouts of precipitation in a 24-48 hour period, we will have to monitor impacts of heavy rainfall occurring over the same area. Precipitable water values will be around 2 inches, illustrating the threat for these storms to be efficient rainfall producers.

A few lingering showers will be possible in the south on Monday, but then we look to dry out briefly as weak high pressure settles in. Monday will bring a relief from the warmth and humidity, as dewpoints retreat into the 40s and 50s, and high temps top out in the 75-80 degree range.

LONG TERM. (Monday night through Saturday) Issued at 247 AM CDT Sun Aug 9 2020

The long term period starts off with high pressure in control giving the CWA a dry, mostly sunny and pleasant Tuesday. High temperatures will be in the low to mid 80s with dewpoints in the mid 50s to low 60s. On Wednesday the high pressure moves off to the east and more humid air starts to return to the area. The chance for showers and thunderstorms returns as well and lasts through the period. There is little agreement amongst the deterministic models on the placement and timing of features, so trying to pinpoint where and when precipitation may occur is tough. The latest NBM has slight to chance PoPs in the grids from Wednesday through the end of the period which seems reasonable at this point. Temperatures will run near or slightly above average with highs in the low to mid 80s and overnight lows mainly in the 60s.

AVIATION. (For the 12Z TAFS through 12Z Monday morning) Issued at 605 AM CDT Sun Aug 9 2020

Widely scattered showers and thunderstorms will affect the TAF sites this morning, with attendant MVFR conditions and the potential for gusty winds. A few strong storms look to flare up over east central MN and west central WI during the late morning and afternoon hours. After that we await thunderstorms along the advancing cold front over the eastern Dakotas to spread into the area this evening. Those will have the potential to be severe as well.

KMSP . Thunderstorms look to be in the vicinity of the aiport at TAF issuance, although an overall waning trend is expected throughout the morning. Also expect high-end MVFR ceilings into early afternoon. Hi-res models are relatively consistent with bringing in another round of strong to severe storms this evening, so have upgraded the Prob30 to a Tempo.

/OUTLOOK FOR KMSP/ Mon . VFR. Wind NW at 5-10 kt. Tue . VFR. Wind SW at 10G15 kt. Wed . VFR. Wind SE at 10G15 kt.

MPX WATCHES/WARNINGS/ADVISORIES. MN . None. WI . None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
