The main story we will be watching this week will definitely be the severe weather, but we will also be monitoring the risk for flooding in the southern Plains, gradually cooling temperatures, and much more in this week’s 5 Things to Watch.
Multi-Day Severe Weather Threat:
Everyday this week will pose the risk for severe weather across some part of the US as multiple rounds of low pressure impacts the Plains before a more-organized and intense low takes over late-week. To begin the week, the best risk for strong to severe storms will be across the southwestern Plains, including much of Oklahoma and the western half of Texas. These threats will include large hail, damaging winds, and tornadoes. The tornado threat should really ramp up on Wednesday into Thursday, however, thanks to a more-developed low pressure system taking control, which will feature all ingredients needed for intense storms. That threat will shift from the southern Plains on Wednesday to the Ohio River Vally, Mid-Mississippi River Valley, and ArkLaTex on Thursday.
Central US Flood Risk:
With frequent storms in the forecast for the southern Plains and even parts of the Midwest, the risk for flooding will be present this week. According to the Weather Prediction Center, there is a Marginal to Slight Risk for excessive rainfall and flooding across parts of the noted regions through at least midweek. No doubt this will bring river levels up and will lead to some flooding. Through Friday, a widespread 3-5+ inches is forecast from coastal Texas up through ArkLaTex and into a large portion of the central Plains and Midwest.
Gradually Cooling Temperatures:
As the main storm system takes over midweek across the middle part of the country, its associated cold front will usher in cooler temperatures by this weekend across most of the eastern two-thirds of the nation. Already to start the week, temperatures will be below average across the Northern Tier — as much as 30F below normal in the northern Plains. Meanwhile in the Southeast and parts of the Mid-Atlantic, temperatures will be up to 10F above average. By this weekend, however, temperatures will become below normal, except for the Southeast coast and Florida, thanks to a cold front moving through. It is quite hot across the South this time of the year, so this cool down will actually be nice.
The spring gloom will persist for yet another week in the Northeast as another round of storms — along with their clouds — sweep through. Monday actually won’t be that ugly of a day, with sun and clouds expected and a few spotty showers. On Tuesday, though, as showers from the next storm begin to move into the interior of the Northeast, clouds should increase in the I-95 corridor and the coastal areas. Following overnight showers, clear skies in the morning will give way to clouds and some showers by the evening on Wednesday before widespread clouds and rain takeover Thursday into Friday. By the time this week comes to a close, many locations can expect 1-2+ inches of rainfall.
Rocky Mountain Snow:
Even though spring is here and summer is on the way, snow is still falling and will continue to fall across parts of the Rocky Mountains this week. Snow will be limited to some of the very highest of peaks early-week until Wednesday, when the new storm forming over the Plains will bring a widespread, moderate snow to much of the Rockies, especially the central portion of the mountain range. This snow should persist through Friday before coming to an end for the most part this weekend. In the peaks, 1-2+ feet of snowfall is forecast this week.
