A storm system working east along the International border has a cold front draped south over the Plains and as usual this is triggering thunderstorms which if they haven’t already, will turn severe as they run into increasingly hot and humid air out ahead. These surface temperatures in the map below greatly raise the lapse rate (measure of temperature difference with […]

While some glorious weather has invaded the Great Lakes and Midwest from Canada with dry air, low humidity and abundant sunshine, this allows the perfect combination of warm, very comfortable 70-degree days accompanied by cool, crisp nights in the 40s with even frost in the UP of Michigan. As we progress towards the later part of this week, this cool, Canadian […]

Today will see plenty of active weather with Texas, the Lower Mississippi Valley and Eastern Seaboard all seeing thunderstorms today. The same mesoscale convective complex which had a derecho on it’s leading edge as it swept southeastwards yesterday producing over 300 wind damage reports across the Mississippi Valley will gradually weaken as it takes aim at New […]

Following highs in the 90s from Minneapolis to DC, an eastbound cold front bringing showers and storms to the Mississippi Valley will continue pushing east over the next 36-48 hours. On it’s backside temps are falling 20-25 degrees from the previous 24 hours ago. While weekend highs soared well into the 90s across the Dakotas, their in the 70s […]

  There are two lines of storms to watch across the US this afternoon, the first line now sweeping southeastwards over the Mid-Mississippi valley extends from southern Illinois down through Kentucky, western Tennessee and into Arkansas. This line has already produced damaging winds, some hail and heavy, flooding rains over parts of Missouri. These cells will continue moving southeast through the […]

Between Thursday and this morning, there are parts of southern Alabama and the Florida panhandle which has seen an astonishing amount of rainfall. While some places have witnessed 15-22 inch 2-day totals, some spots have witnessed 12-18 inch ONE-DAY totals. These are amounts you would expect from a tropical storm or hurricane but of course […]

The trough remains in place over the Northeast but it’s days are numbered as the next Pacific storm roars into the Northwest Friday bringing yet another reinforcing shot of autumnal chill, rain and mountain snows, this atmospheric shove will help raise heights further east and will force a ridge back into the Northeastern part of the […]

We have yet another push of unseasonably chilly air driving into the Pacific Northwest by Friday as the next powerful Gulf of Alaska storm comes ashore. Prior to the storm’s arrival, we see heat build over the Deserts and by the time we reach Saturday and the storm has already come ashore over Washington, the heat core […]

Over the next 3-5 days we will continue to see a rather blocked, congested weather pattern over North America with a trough over the Northwest and a large trough which extends from the Great Lakes all the way down to the Carolinas. A high over Hudson Bay will keep the cool flow going with highs again […]
