We've been stuck in a pretty stagnant pattern recently. With a few cut-off lows and strong ridges of high pressure, the day-to-day pattern has struggled to change much. The trough in the Pacific Northwest will try to change that later this week.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 133452-1747164978339.png">This trough will spark storms on the High Plains Wednesday before closing in on the Middle Mississippi River Valley late this week.<h1>OVERVIEW</h1>As this trough swings in, it will run into VERY warm temperatures. By Wednesday and Thursday, highs across the High Plains will get back to the 80's and 90's. The warm and humid air will more than likely help power strong to severe storms later this week.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-11 103741-1746981482962.png">While a few ingredients look to come together sometime around Thursday, a lot can still change between now and then. The Storm Prediction Center has highlighted areas around the Chicagoland later this week.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-12 063317-1747053207873.jpg">As details become a little clearer throughout the week, things like timing and storm mode will become a little clearer too.<h1>WEDNESDAY</h1>As our cold front swings in, strong storms will be possible during the day. Areas from North Dakota to Nebraska will have to watch out for damaging winds, large hail, and a few tornadoes. However, we expect the tornado window to be fairly narrow in the afternoon.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 133510-1747164997378.png">Through tonight, a cold front swings through and there is an isolated chance for severe storms. On Wednesday, as this front really taps into moisture feeding from the Gulf and unseasonably hot temperatures, the storm threat looks to be more promising.<video src="https://media.weathernationtv.com/app/uploads/2025/05/05-13 tue wed-1747165177936.mp4" controls="true" width="100%"></video><h1>THURSDAY</h1>This is where things get interesting. The amount of unstable air makes ANY forecaster nervous to say this: the cap looks like it should win vs the worst of the worst environments.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 070147-1747141345956.png">What does that mean? If storms fire in southern Illinois, southern Indiana, or western Kentucky, they could become violent. Where we expect storms to develop is where the Storm Prediction Center has issued a SLIGHT risk for severe storms on Thursday:<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 133456-1747165003739.png">What to expect: A cold front should be able to beat any capping inversion eventually, but that normally means a line of storms to track, not discrete cells. One of these organized clusters of storms normally rolls through in July &amp; August, but something like that is where we'd be leaning right now.What to do: If you live more in the Midwest, in Indiana, Illinois, or Kentucky, pay attention. Check back with the forecast, because some concerning ingredients could be in play. Right now, it's still a touch too early to know that a cap will keep a lid on storms.<video src="https://media.weathernationtv.com/app/uploads/2025/05/05-13 tue wed-1747165057243.mp4" controls="true" width="100%"></video><h1>FRIDAY</h1>A lot of this will depend on what happens Thursday, so take this with a grain of salt. As the front continues to sag southward, expect more storms by the afternoon and evening. Friday is about when we might need to start talking flooding too, with multiple rounds of storms hitting similar areas at that point.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 070719-1747141650294.png">

Severe Weather Ramps Up Late Week

Here we go. Whoever wanted it to be Summer already got their wish down on the Southern Plains. Texas is heating up in a serious way as a strong ridge noses into the picture.Over 110 stations across the U.S. could break records from today through Sunday. We expect this to be a prolonged heat wave, especially for those in Texas.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 132927-1747164609655.png">Temperatures will range between a few degrees above average to 30 degrees above average through the end of the week.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 132922-1747164711264.png">The National Weather Service (NWS) has upgraded heat advisories to extreme heat warnings across Texas. This includes cities such as San Antonio, where records could fall for days on end.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 132941-1747164754899.png">Temperatures in San Antonio are likely to remain above 100 degrees all week long, outlooks project all the way through Sunday.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 132948-1747164789343.png">With heat as intense as this, on a scale of limited to extreme, there are areas in Texas that will max out the scale this week with extreme heat danger expected. <img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 132937-1747164803848.png">Don't like it to be this hot this early? I might have some bad news for you...long range forecasters like keeping this sort of pattern around for the middle and end of May. Does this mean it's going to stay this hot? Not necessarily - these temperatures outlooks are more confidence-based on below or above average. Not to what degree. It's usually 86 in Austin for the record.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 074146-1747143750139.png">How do you stay safe in this kind of heat? You have to remind yourself how early it is in the season for it. Your body is not adjusted to it coming out of Winter. The first big hot stretch of the year can always feel worse on the body and mind. Drink water early and often and don't push yourself too hard!<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 074710-1747144046862.png">

A quick-moving storm system that brought <a href="https://media.weathernationtv.com/news/reports-of-damage-after-tornado-warned-storms-hit-new-england/">tornado warnings to southern New England</a> Tuesday will coat northern New England in a blanket of fresh snow into Wednesday.  In fact, the higher elevations of New Hampshire endured heavy snow and high wind as early as Tuesday afternoon.

https://twitter.com/MWObs/status/1054847256728346624

Northern New Hampshire and non-coastal Maine will receive the highest snowfall amounts from winter's glancing blow.  It should come as no surprise since temperatures are certainly cold enough.

https://twitter.com/NWSCaribou/status/1054732074555531266

Temperatures are expected to remain in the 30s for afternoon highs on Wednesday.  Winter Weather Advisories and Winter Storm Warnings are posted for several counties in northern New England where heavy, wet snow is forecast.

From late Tuesday night through Wednesday, snow will pile up between 3 and 7 inches.  A few locations could potentially pick up 10 inches of snow.

Heavy bursts of snowfall may reduce visibility for the morning drive to work, with snow lingering in some areas for the afternoon drive home.

Looking ahead, the potential for the season's first Nor'easter is on the horizon by the weekend.  A low pressure in the Gulf of Mexico bringing rain to states like Texas will move east through Florida by Friday.  This low will track up the East Coast during the weekend and bring heavy rain, gusty wind, high surf, and the potential for beach erosion.

https://twitter.com/NWSEastern/status/1054852199145185280

While temperatures will remain above freezing for many, some of the higher mountains in the interior Northeast may pick up some snow.  Be sure to follow <a href="https://media.weathernationtv.com/">WeatherNation</a> as we track this potential Nor'easter.
