Lakes, Sat, Jan 15.
- Heavy precipitation across portions of mainland Alaska, Thu, Jan 13.
- Heavy precipitation across portions of the Alaska Panhandle and mainland Alaska, Fri, Jan 14 and 
Sun, Jan 16.

- High winds across portions of the Alaska Panhandle, Fri through Sun, Jan 14, 15, and 16.
 
Detailed Summary:

High pressure over the Rockies on Thursday combined with low pressure moving over the Plains on 
Friday will produce a strong pressure gradient over the Central High Plains and adjacent areas on 
Thursday into Friday. The associated pressure gradient will create an area of High Winds over the 
region on Friday, with the wind beginning to increase on Thursday. Furthermore, as the area of low 
pressure moves southeastward to the Middle Mississippi Valley by Saturday, Heavy Snow will develop 
over parts of the Upper/Middle Mississippi Valley and the Upper Great Lakes on Friday.

Similarly, low pressure off the Mid-Atlantic Coast and high pressure near James Bay in Canada will 
produce a strong pressure gradient over parts of the Northeast and along the Northeast Coast for 
Friday. Therefore, an area of High Winds is depicted on the Hazards Chart over parts of the 
Northeast into the northern Mid-Atlantic on Friday. In addition, the area of high pressure over 
parts of Eastern Canada and the low off the Northeast/Canadian Maritimes Coast will pull cold air 
southward over the Northeast on Saturday. As a result, low temperatures will be in the single 
digits below zero to ten below zero temperatures over northern Maine on Saturday morning. 
Therefore, an area of Much Below Normal Temperatures is on the Hazards Chart on Saturday.

Over Alaska, an area of deep low pressure south of the Aleutians will have a strong pressure 
gradient associated with the low, producing an area of High Winds over the Alaska Peninsula by 
Thursday. Moisture associated with the low will create an area of Heavy Precipitation over parts of 
the Kenai Peninsula, Afognak and Kodiak Islands, and the land on the Alaska Peninsula across from 
Kenai Peninsula and Afognak and Kodiak Islands on Thursday. 

On Thursday, another area of low pressure over the North Pacific will move into the Gulf of Alaska 
by Friday. The associated pressure gradient will produce an area of High Winds over the Alaskan 
Panhandle on Friday and Saturday. The system will also stream moisture into the panhandle, creating 
an area of Heavy Precipitation over the region on Friday. Furthermore, a third area of low pressure 
over the North Pacific will move into the Gulf of Alaska by Sunday. Again, the low will stream 
moisture into the Alaskan Panhandle, producing another area of Heavy Precipitation across the 
panhandle on Sunday. Moreover, the pressure gradient associated with the low will also create an 
area of High Winds over the panhandle on Sunday.
