Southeast Alaska Forecast Discussion National Weather Service Juneau AK 544 AM AKDT Fri Apr 10 2020

SHORT TERM. After a brief return to winter earlier in the week, spring is once more on track to make itself felt throughout the panhandle. No major weather systems are expected to impact SE Alaska through the weekend, and the primary story will be one of warming temperatures.

As a ridge builds across the Gulf in the upper levels, drier air will make its presence felt throughout the panhandle over the next few days. This airmass should prohibit the formation of any widespread cloud cover, which will enable the longer hours of sunlight and increased sun angle to make their impact felt across SE Alaska. After a chilly start on Friday morning, temperatures will climb up into the mid 40 and 50 degree range through the afternoon, with the warmest temperatures being in the southern panhandle. Friday night, a large diurnal gradient will be present as clear skies will allow heat to radiate back into the atmosphere, helping to bring temperatures back into the 20s and 30s into Saturday morning.

Saturday will be largely similar to Friday, with the ridge aloft continuing to encourage clearer skies through SE Alaska. Models are indicating that temperatures will continue to warm throughout the atmospheric column during this time period, enabling a slow warming trend to make itself felt at the surface as sun and offshore flow continue. Sunday will see increased cloud cover as flow turns towards a more southerly direction, bringing a renewed influx of moisture. However, am not expecting any real precipitation with this during the forecast period, and given the warm air advection associated with the southerly flow, think that it is safe to expect another warm spring day to wrap up the weekend.

Only minimal changes were made to the forecast, primarily increasing daytime high temperatures across much of the panhandle over the next few days. Confidence remains high for a low-impact pattern.

LONG TERM. /Sunday through Friday / . As of 10 PM Thursday . The long term features a blocking mid level ridge over the west coast of North America with its axis running straight through the Panhandle. Through the week, multiple systems will try to make their way up and over the ridge increasing clouds and the chance for rain along and to the west of the ridge axis. Where exactly the axis of the ridge sets up will determine which areas will have the best chance for rain and which area will remain mostly dry. Current thinking is that Yakutat and areas along the northeast gulf coast will have the best chance for rain through the week as flow remains onshore.

Models are coming into better agreement with the timing and placement of the short waves moving northward around the west side of the ridge through the week. A weak front moving northward through the gulf will impact the northern and northeast Gulf Coast on Sunday increasing rain chances. Multiple waves will follow a similar path each day through the week. Yakutat will most likely be the wetter part of the region while the southern and eastern portions of the Panhandle remain relatively dry with lesser chances for precip. Models usually struggle with systems breaking down blocking ridges, so would not be surprised to see guidance having issues with the placement of the ridge axis or the systems in the gulf by the latter half of next week.

With the flow coming out of the south and west, a warming trend is expected to take place. Temperatures at 850mb expected to be around 0C to +3C through the week translating to surface temperatures in the 40s and even 50s for highs. Diurnal spreads will be largest at the beginning of the period due to drier air in place and less cloud cover. By the latter half of the week clouds and moisture should increase which will moderate temps some.

Winds through the period are expected to remain relatively light over the Panhandle and through the inner channels as high pressure will keep the gradient weak. Winds may increase along the northern and northeast gulf coast as the shortwaves move through; but the finer details and timing will be worked out as we get closer in time.

Kept with ensemble solutions for the long range and relied heavily on WPC and the NBM with any forecast changes. Confidence showing some improvement due to models beginning to fall in line, however would not call it high confidence.
