US Day 3-7 Hazards Outlook
NWS Weather Prediction Center College Park MD
234 PM EST Mon Feb 07 2022
 
Valid Thursday February 10 2022 - Monday February 14 2022
 
Hazards:
- Heavy precipitation across the northern portion of the Alaska Panhandle, Fri-Sat, Feb 11-Feb 12.
 
Detailed Summary:

Relatively tranquil conditions with little in the way of hazardous weather can be expected through 
the medium-range period.  While the basic upper-air pattern across North America remains similar to 
that in recent weeks, the broad northern stream trough is forecast to retreat further north leading 
to less chance of it interacting with the southern stream flow coming up from the Gulf of Mexico 
toward the southeastern U.S.  Only a couple of areas will be marginally close to hazardous weather 
consideration.  A clipper low pressure system is forecast to deliver a period of snow from northern 
Minnesota to the Great Lakes Friday into Saturday.  The highest chance for the snow to accumulate a 
few inches will be near the Canadian border of northern Minnesota.  Behind this clipper, a shot of 
arctic air is forecast to drop temperatures to 15-20 degrees below normal across lower Michigan and 
into the northern portion of the Ohio Valley on Sunday.  Elsewhere, the most recent 00Z run from 
the ECMWF indicated the possibility of cyclogenesis near the East Coast early next week as the 
northern and southern stream troughs manage to interact.  This scenario represents the western-most 
outlier with respect to this system.  Therefore, no areas of hazardous weather have been considered 
for the East Coast at this time.

For Alaska, the frequent influx of Pacific moisture toward southeastern Alaska through the 
Panhandle in the short-range period is forecast to relax by the time the medium-range period begins 
on Thursday.  By later on Friday into Saturday, the next moisture plume associated with a 
triple-point low is forecast to bring heavy precipitation mainly across the northern portion of the 
Panhandle.  By early next week, models have been indicating a bigger storm system to move across 
the Aleutians.  It appears that this system will not be strong enough to generate winds of 50 knots 
or higher over a significant area.  Therefore, no areas of high winds have been indicated for the 
Aleutians at this time.
