Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 145 PM EST Mon Jan 27 2025 Valid 00Z Tue Jan 28 2025 - 00Z Thu Jan 30 2025 ...Slow moving storm to push east from Southern California into the Southwest... ...Locally heavy snows expected across the Great Lakes into portions of the Northeast and New England... ...Above average temperatures expected across much of the Central to Eastern U.S., while below average temperatures stretch from Southern California into the Southwest... A slow moving upper low that brought some much needed precipitation to Southern California over the weekend will be pushing slowly eastward over the next few days from Southern California through the Southwest. This system, however, will become increasingly moisture starved over the next few days as it pushes into the Southwest. Subsequently, precipitation amounts are expected to be lighter over the Southwest Tuesday-Wednesday than what was observed over Southern California this past weekend. This precipitation over the Southwest will bring little in the way of relief to the ongoing drought conditions over Arizona and New Mexico. There will be potential for more widespread heavy precipitation with this system late Wednesday into Thursday across the Southern Plains into the Lower Arkansas Valley as high moisture values feed into this system from off the western Gulf. This slow moving upper low will keep temperatures below average on Tuesday from Southern California into Arizona, with these below average temperatures spreading east into much of New Mexico on Wednesday. In contrast to the below average temperatures across Southern California into the Southwest, temperatures are expected to remain well above average over the next few days across much of the Central to Eastern U.S. High temperatures are forecast to be 10 to 20+ degrees above average over these regions Tuesday and Wednesday. Despite the widespread much above average temperatures expected across the Central to Eastern U.S., there are not expected to be many record high temperatures, with only a few forecast across South Dakota, North Dakota and Iowa on Tuesday. More typical wintry weather on tap across the Great Lakes into portions of New York State and New England over the next few days as two winter system affect this region. The initial system will be a strong cold front dropping southeastward through the Great Lakes Monday night and through New England early Tuesday. Snow squalls are possible along and ahead of this strong front from the Great Lakes into the Northeast, producing intense short term snowfall, along with gusty winds, poor visibility and dangerous driving conditions. This will then be followed by an area of low pressure pushing southeastward from the Upper Great Lakes Tuesday afternoon into northern New York State and New England on Wednesday. This low will bring the potential for accumulating snows from the Upper Peninsula of Michigan, the northern portions of the Lower Peninsula of Michigan, much of western to northern New York State, western Massachusetts, into much of Vermont and New Hampshire.
