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.
