A blast of heat blasted across the Plains into the Midwest Tuesday, torching many records along the way. The heat will fade today as it reaches the mid-Atlantic.
After a long period of time with wave after wave of arctic blasts coming out of Alaska and western Canada, there will finally be an arctic disconnect later this week and this weekend, meaning a warmer pattern going forward for a time.
The next 72 hours will be wet from the southern Plains to the Northeast. Following a strong cold front, it will turn much cooler with a danger of frost Sunday night and again Monday night from the Midwest to the interior mid-Atlantic and Northeast.
The persistently cold weather pattern for much of the spring season will repeat itself this weekend as another strong cold front ushers a very chilly air mass into the Plains and to the East Coast this weekend and early next week.
The wild weather will continue the next couple of days from the Plains on east as a strong upper-level low pressure area pulls very cold air for so late in the season all the way to the Rio Grande Valley. It will lead to a wet weekend from the mid-Mississippi Valley to the Southeast.
An upper level storm forming over the Plains in the next 36 hours will pull more very cold air into the Rockies and Plains, producing a very late season snow fall. Flooding rains may also occur farther east over the Mississippi Valley and into parts of the Midwest as the storm develops this week.
Even though May begins Wednesday, it will begin with snow in parts of the eastern Rockies, with temperatures 15 to 25 degrees below normal up and down the Plains later this week.
