Area Forecast Discussion . UPDATED National Weather Service Twin Cities/Chanhassen MN 653 AM CDT Thu Jul 29 2021

SHORT TERM. (Today through Tonight) Issued at 421 AM CDT Thu Jul 29 2021

Observations across the northern half of Minnesota confirm the Canadian smoke is advancing south as expected. Visibilities as low as 3/4 to 1 mile are being reported in places. Interestingly, overcast skies are being reported from several METARs across central Minnesota along the leading edge of the visibility reductions. Satellite is void of any cloud cover, therefore this is likely dense smoke just above the surface that will gradually descend within a broad area of subsidence during the next several hours. The HRRR-smoke model continues to have a good handle on this batch of smoke with both areal extent and density. Followed that guidance closely through tonight. Surface smoke concentrations are maxed out in that output, so expecting very poor air quality and a period of low visibilities from north to south today and early evening. Flow will turn more easterly tonight and push the smoke over the Dakotas.

LONG TERM. (Friday through Wednesday) Issued at 421 AM CDT Thu Jul 29 2021

A short wave diving southeast across the northern Plains tonight and into the Mid Missouri Valley Friday will generate widespread showers and thunderstorms. Unfortunately for many, it will miss us to the south and be confined mostly to Iowa and Nebraska. There could still be a few showers or storms grazing southern Minnesota, so maintained 20-30 PoPs for those areas for now, but that could be pulled in later forecasts.

Northwest flow will prevail through the rest of the period as the ridge centers itself over the southwestern U.S. again. Several short waves embedded in the northwest flow will pass through, but dry and stable air will prevent any thunderstorm development with them. Temperatures overall will average about normal into the middle next week, but a short period of cooler than normal temps are likely Sunday and Monday.

AVIATION. (For the 12Z TAFS through 12Z Friday morning) Issued at 653 AM CDT Thu Jul 29 2021

MVFR or IFR visibilities due to smoke will be the main story today at all the MN TAF locations. Some LIFR visibilities are also possible this morning at STC. The smoke will clear from north to south this evening with a return to VFR conditions for the rest of the period.

KMSP . The smoke has begun to reach MSP already. The most concentrated smoke should miss the terminal just to the west, but it is possible IFR visibilities could briefly impact the area this afternoon.

/OUTLOOK FOR KMSP/ Fri . VFR. Winds SE 5-10 kts becoming SW. Sat . VFR. Winds NW 10-20 kts. Sun . VFR. Winds N 10 kts.
