Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 110 PM AKDT Wed Jul 8 2020

SYNOPSIS. A front over the Western Interior continues to bring wetting rains and cool weather to that area as the front pushes into the Central Interior. An upper level low Just east of Northway will continue to push south into the Gulf of Alaska tonight. A strong shortwave rotating around an upper level low over Banks Island will push south over the Central and Eastern North Slope this afternoon, the Central and Eastern Brooks Range tonight, and the Central and Eastern Interior tomorrow. This upper level feature will be the focus of attention tomorrow as it merges with the front over the Central Interior tomorrow. An active thunderstorm day is expected tomorrow over the Central Interior mainly to the west of Fairbanks with many storm producing frequent lightning, gusty winds and small hail.

DISCUSSION. Models, the 12z model suite initialized well against the 12z surface analysis and verified well against the 18z surface analysis. Models are in reasonable agreement on the position and strength of major features but do show spread on deep layer moistures associated with the shortwave moving south over the Central and Eastern Brooks Range tonight and over the Central and Eastern Interior tomorrow, with the ECMWF showing driest solution and NAM and GFS with a more moist profile. Given today's verification and combined with better verification with the HRR model with ongoing weather, we opted to lean on a NAM and GFS blend. Given the more moist profiles, more clouds and less day time heating, as well as slightly quicker and further west track we keep the area of greatest instability and strongest thunderstorms just west of Fairbanks tomorrow afternoon and evening.

Central and Eastern Interior . Mostly cloudy skies and showers continue mainly to the west of Fairbanks. There will be very marginal instability but enough for isolated thunderstorms late this afternoon and evening, favoring the southern Brooks Range.

Thursday is expected to be an active thunderstorm day over the Central Interior with the area of greatest instability stretching from near Stevens Village southward to near Lake Minchumina. Given forecasted instability values tomorrow afternoon any of the thunderstorms in this area will be capable of producing strong winds, hail, heavy rain and frequent lighting. The strength and coverage of the storms will be very dependent on mid level clouds and early initiation of storms off the higher terrain as well as the timing of the upper level wave disturbance. Rain will likely continue well into Friday morning across parts of the Alaska Range and Interior south of the White Mountains.

North Slope and Brooks Range . The couple of will continue to remain similar as periods of fog and stratus move onto the coast. Thunderstorms will be possible along the northern foothills of the Brooks Range this afternoon and evening.

West Coast and Western Interior . The front that brought wetting rains, cloudy and cool weather over much of the West Coast and Western Interior will continue to weaken in place this evening. A transition to northerly flow will develop overnight with drying conditions and decreasing clouds for Thursday and Friday. Expect gradual warming, as well.

Coastal Hazard Potential Days 3 and 4 . None.

FIRE WEATHER. Wet and damp conditions along the West Coast will transition to northerly flow aloft with a drying and warming trend for Thursday and Friday. Over the Interior, a few isolated thunderstorms will develop this afternoon and continue into the evening over the high terrain.

Attention turns to the possibility of an active thunderstorm day on Thursday over the Central Interior with the area of strongest storms and concerns for frequent lighting from near Stevens Village southward to near Lake Minchumina. Lightning Activity Levels of 3 are forecast currently for portions of the Central Interior with anticipation of mid level clouds preventing optimal afternoon heating. If fewer clouds verify, and with the forecasted instability an Lighting Activity Level of 4 is possible tomorrow afternoon and evening to the west of Fairbanks. Will continue to monitor. Any storms that do develop tomorrow are expected to be wet.

HYDROLOGY. No major concerns at this time.

AFG WATCHES/WARNINGS/ADVISORIES. None.

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.
