Wildfire smoke engulfs the Twin Cities and rain isn't helping
Wildfire smoke engulfs the Twin Cities and rain isn't helping originally appeared on Bring Me The News. The worst air quality in Minnesota Tuesday morning is in the Twin Cities metro area. Not even the morning rain is enough to prevent thick, near-surface smoke from reaching a "very unhealthy" level. It literally smells like campfire in the Twin Cities. Why isn't the rain helping clear out the smoke? According to the National Weather Service, the smoke is arriving behind the cold front that is delivering the rain, so the smoke "filters right back down." Sign up for our BREAKING WEATHER newsletters The purple on the map below represents the areas experiencing "very unhealthy" air quality, which is level five of six on the Air Quality Index (AQI) scale. With an AQI in the purple zone, people with heart or lung disease, older adults, children and teenagers are advised to avoid physical activities outdoors. Everyone else is urged to avoid strenuous outdoor activities, limit time outside and consider moving physical activities indoors or rescheduling them. The awful air quality is due to heavy smoke from wildfires in Canada that continue burning out of control. And the smoke is going to stick around all day Tuesday, The HRRR forecasting model shows where near-surface smoke could be heaviest between 8 a.m. and 8 p.m. Take a look: "The front will continue to slowly move from northwest to southeast throughout the day on Tuesday, with smoke impacts eventually becoming statewide," the MPCA and NWS say. The air quality alert is in effect until noon Wednesday, at which point Minnesota is forecast to enjoy a beautiful day with clear, smoke-free skies with high temps in the 70s.

UPDATES: Monday's severe weather threat
SHREVEPORT, La. (KTAL/KMSS) – Much of the ArkLaTex will stay dry on Monday and Monday evening; however, strong to severe storms will be possible over the extreme northern edge of the area. All severe weather threats are possible, including very large hail, damaging wind in excess of 70 mph, and a tornado or two. Scroll down for frequent radar updates as storms develop. Storm timing and location: Above is the very latest update from the HRRR model, which creates a new forecast every hour. It gives some guidance concerning where and when the storms could develop. As of this writing, the HRRR and most other models show the risk of storms will be highest over McCurtain, Sevier, and Howard Counties. It's possible that most of the rest of the area could stay dry.

Bullseye for severe storms Thursday moves closer to the Twin Cities
Severe storms could come in the form of two rounds Thursday. The first could be leftovers from a line of storms in South Dakota early Thursday morning, and the second could be redevelopment in the afternoon across eastern parts of Minnesota into Wisconsin. The Twin Cities are on the line of a marginal and slight risk (levels 1 and 2 on the severe scale), while the bullseye is a level 3 of 5 enhanced risk in Wisconsin. Below is the previous severe weather outlook for Thursday. Clearly, the Storm Prediction Center is sensing a northwesterly shift in the area of concern. "Models are in good agreement depicting a strong convective signal near the MN/WI border by [3 p.m. CT] or so, with increasing coverage points east through evening," says the Storm Prediction Center. The SPC says all of the signals at this time point to supercell storms in the enhanced risk area, including potential for a strong tornado. The high-resolution models aren't quite picking up on the potential storm evolution for Thursday afternoon just yet, but the European model's lightning simulation suggests there could be an arc of storms moving southwest to northeast across southeastern Minnesota into the enhanced risk in Wisconsin. The Significant Tornado Parameter from the HRRR, which only goes out through 1 p.m. Thursday, and the NAM 3km model, are somewhat similar, though the NAM 3km is a bit further east with the better environment for tornadoes. This can and likely will change over the next 48 hours. Thursday isn't the only day for severe weather. Wednesday could see storms spark in the Dakotas, and those cells could track into southwestern Minnesota overnight into Thursday morning. Here's the HRRR model's radar simulation from 3 p.m. Wednesday through 1 p.m. Thursday. You can see a bowing line of storms blasting through South Dakota and moving near the Minnesota-Iowa border by early Thursday. How long that line of storms stick around on Thursday will likely play a big role in determining where severe weather is most likely with redevelopment Thursday afternoon. We'll keep you updated as the forecast changes.

Dry for most, but for how long?
SHREVEPORT, La. (KTAL/KMSS) – Much of the ArkLaTex received over two inches of rain on Tuesday. Wednesday has been a mainly dry day for most of the ArkLaTex. The big question is, how long will it last? Futurecast outlook for the next 36 hours Could we stay dry on Thursday? Most hi-res models show that the answer will probably be yes! Futurecast shows that we will see a mostly cloudy sky on Wednesday night with a very small chance for a spotty shower. It shows that we will continue to see lots of clouds with a few peeks of sunshine on Thursday. It is possible that we could see a few isolated showers or thunderstorms over the eastern quarter of the area, but that chance is looking very low. Other models, including the morning run of the HRRR, show that the entire area will stay dry on Thursday. That will not be the case on Friday. The main upper-level disturbance will be to the east of our area, and we will likely see some scattered t'showers move through much of the area. This rain will decrease Friday night and Saturday, with some sunshine returning late Saturday. Rainfall totals will probably be 1/10'. Tomorrow's Forecast Thursday temperatures: We likely won't see much change in temperatures on Thursday. Lows will likely be in the mid to upper 50s over the northern half of the area and the low to middle 60s over the south. Daytime highs will remain in the mid to upper 70s over the north and the low to middle 80s over the south. 10-Day Forecast for Shreveport Ready for some heat and humidity? Once any leftover rain moves out of the area on Saturday, we will settle into a dry weather pattern that could last for nearly two weeks. Temperatures will begin the period with highs in the 70s and lows in the 50s. We will see a warming trend next week. Highs will end up in the low 90s by the end of the week. Lows will warm close to 70. Once the heat and humidity settle in, they will stick around through next weekend and probably all of next week. Hello summer!

Front to bring STORMS Sunday evening
A cold front will be moving through the ArkLaTex on Sunday night bringing the threat of strong to severe storms. Below is the latest 18-hour forecast from the HRRR model that shows where the storms will develop and how they will move across the area. The HRRR shows that the storms will probably bring gusts of 30 to 50 mph. However, a few gusts of over 60 mph will be possible. Large hail will be another threat we could face. Here is the latest on hail potential from Futurecast. Quarter to half-dollar-sized hail will be possible in the strongest storms mainly this evening. We will see the storms move out of our area after midnight Sunday night. Copyright 2025 Nexstar Media, Inc. All rights reserved.
