Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 341 PM AKDT Mon Jun 1 2020

SYNOPSIS. High pressure north of the Arctic Coast combined with a thermal trough stretching across Alaska near 64N will be the main weather factors the next several days. The highest impact weather will be the east winds of 20-30 kt and fog and stratus persisting over the Arctic Coast the next several days, along with the Isolated to scattered afternoon/evening thunderstorms along and south of the thermal trough, along with areas if widespread showers, persisting through Thu. The showers will bring up to another 0.25-0.50 inch of rain over much of the area south of 64N through Wed .

The Northern Interior has Red Flag warnings through this evening for hot, dry and breezy conditions. With temperatures and winds decreasing Tue do not expect red flag issues later this will other than potential for thunderstorms. The thermal trough will drift slowly north through the week with thunderstorms inching north in areal extent.

Expect cooling at the surface over the Eastern Interior on Tue, while the North Slope and West Coast/Wrn Interior temps see little change Tue, and most areas will cool a bit more Wed, then see a warm up Thu most areas. A low approaching the West Coast Thu and Fri will bring cooler, cloudier and wetter conditions to the West Coast Thu and Fri.

Aloft . A rex block has now set up over Alaska with a strong high located over the North Slope and a deep low over the Gulf of Alaska. Several weak short waves are moving east across the Southern Interior and West Coast this week bringing bands of showers to the southern Interior and West Coast. The added moisture with this showers will cause isolated to scattered PM thunderstorms to form in the unstable airmass between the bands of showers today and Wed. The ridge will build slowly from Tue through Thu causing conditions to be slightly less unstable from Wed through Thu and decrease the number of thunderstorms Wed into Thu.

This long wave pattern will result in above normal temps and dry conditions over the Northern Interior and North Slope, and near normal temps along with showers and isolated to scattered showers over the Southern Interior and West Coast, with showers and thunderstorms becoming less numerous Wed and Thu and conditions become less unstable due to building ridge aloft.

A low aloft approaching the West Coast from the Bering Sea on Thu will bring showers and cooler temps to the West Coast Thu into Fri.

850 Temps range from 4C along the Arctic Coast and over the southern Interior, with +10C over NW Alaska. Expect cooling of 2-4C over the Eastern Interior on Tue, while the North Slope and West Coast/Wrn Interior temps see little change Tue, and most areas will cool another 1-2C on Wed, then see a warm up Thu most areas, except the West Coast which will cool significantly on Thu as a low approaches from the west.

Surface . High pressure north of the Arctic Coast of Alaska will persist through Thu. This is causing east winds 20-30kt along with stratus and fog along the Arctic Coast that will persist into Wed or Thu.

A thermal trough that lies from Gambell to Nome to Eagle with a second trough from Galena to Point Hope will persist through $am Wed, and then drift slowly north through the week. Isolated to scattered PM thunderstorms that will form along in the unstable airmass along and south of these thermal troughs today and Tue, with the area of thunderstorms inching north through the week. Will periods of widespread showers over the southern Interior south of these troughs through Wed. With conditions becoming slightly less unstable Wed and Thu, the number of thunderstorms will be reduced Wed and Thu. The showers will bring up to another 0.25-0.50 inch of rain over much of the area south of 64N through Wed.

DISCUSSION. At 12Z, all models initialize 10-20 meters too low on h500 heights over Northern Alaska. Models show very similar solutions aloft through 4pm Thu, with good agreement into the weekend.

With precip, the GFS and ECMF show a broader areal coverage of showers today through Wed than the NAM, and are preferred as the area of showers has been broader than the NAM represented the past several days. By Thu the NAM and ECMF better represent showers approaching the West Coast from the incoming low. Will use a blend of the GFS and ECMF for areal coverage through Wed, then a blend of the ECMF and NAM for Thu.

At the surface at 18Z, models verify well with analysis. Models show similar solutions at the surface through Thu, and even into the weekend.

Bottom line is we will use a blend of the GFS/ECMF/NAM for winds and temperatures through Thu, a blend of the GFS and ECMF for precip areal coverage through Wed, then a blend of the NAM and ECMF for precip on Thu.

Coastal Hazard Potential Days 3 and 4 . None.

Fire Weather. The thermal trough that lies from Nome to Eagle with a second trough from Galena to Point Hope will persist through Tue then drift slowly north through the week. Isolated to scattered PM thunderstorms that will form along in the unstable airmass along and south of these thermal troughs today and Tue, with the area of thunderstorms inching north through th week. With conditions becoming slightly less unstable Wed and Thu, the number of thunderstorms will be reduced Wed and Thu. Today should be like Sun, with another 3000 or more lightning strikes in the same areas. Tue will see slightly few strikes, but Wed and Thu should see much less lightning. Expect wetting rains through Wed over most of the area south of 64N North Latitude.

The Northern Interior has Red Flag warnings through this evening for hot, dry and breezy conditions between the Kobuk and Yukon Rivers and west of Bettles. With temperatures and winds decreasing Tue, do not expect red flag issues later this week other than potential for thunderstorms. The thermal trough will drift slowly north through the week with thunderstorms inching north in areal extent.

Hydrology . Flood is occuring at the Kuparuk River Bridge, but the ice jam is reported to have moved out and water water levels are dropping. The flooding is expected to end Tue at the Kuparuk River Bridge.

Warm temperatures in the Brooks Range will continue rapid snow melt this week, so high water levels will continue over the North Slope Rivers. Rivers on the North Slope with ice remaining in them, such as the Colville River near the Coast, could still see ice jams this week and should be alert for possible flooding.

Over the Interior and West Coast, 0.25-0.50 inch of rain over much of the area south of 64N is expected through Wed and will cause rises on rivers in the southern Interior. About 0.75 inch of rain fell over the Eastern Alaska Range Sun, with another inch there through Wed, so rivers draining the Alaska Range should see sharp rises. No flooding is expected at this time.

AFG WATCHES/WARNINGS/ADVISORIES. Flood Advisory for AKZ203 at Kuparuk River Bridge.

Red Flag Warning for AKZ208-AKZ209-AKZ216-AKZ217-AKZ219.

Small Craft Advisory for PKZ210-PKZ230.

Brisk Wind Advisory for PKZ235-PKZ240-PKZ245.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
