Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 159 PM AKDT Tue May 26 2020

SYNOPSIS.

A cloudy and showery weather pattern encompasses most of the Mainland today. Temperatures are actually running slightly below average, but this current pattern did bring in some much needed rainfall to parts of the Interior, along with some locally heavy rain across the Alaska Range. This pattern will persist through tomorrow and then gradually warm through the end of the week.

DISCUSSION.

Upper Levels and Analysis . A moderately strong blocking high centered over the North Slope is dominating the upper air pattern. "Easterly" waves disturbances rotating around the underside of the ridge are responsible for the extensive clouds, cooler temps, and showery weather regime across most of the Mainland today. Otherwise, extensive stratus and fog reside over the North Slope with some clearing over the Fortymile area where upper ridging is reasserting itself behind the aforementioned easterly wave moving into the Western Interior/West Coast.

West Coast and Western Interior . Showers and a possible isolated thunderstorm over the Interior will be possible late this afternoon and evening as an "easterly" wave traverses the region. On Wednesday, cold air advection associated with a trough over the Bering Strait will steepen low level lapse rates, so more showers and inland isolated thunderstorms will be possible. Thursday will gradually dry out and warm up as ridging aloft builds in and low level flow becomes north-northeasterly.

North Slope and Brooks Range . Showers and afternoon isolated thunderstorms will be possible along the Brooks Range the next three days. The most active day looks to be tomorrow afternoon as a shortwave trough moves across the Range from the south, with some of these showers spilling over to the Slope. Other than that, the usual persistent low stratus and fog will continue along the Arctic Coast.

Central and Eastern Interior . Rain showers with isolated afternoon thunderstorms will be possible each afternoon, although shower coverage will be greatest today with a gradual decrease Wednesday and Thursday and Friday. A gradual increase in temps will also occur as upper ridging slowly rebuilds and low level flow turns northeasterly Thursday evening and increases Friday. By Friday expect temps to rebound back above average.

Coastal Hazard Potential Days 3 and 4 . None.

FIRE WEATHER. A remnant thermal trough will support isolated/slight chance of thunderstorms today and Thursday afternoon across the Interior, although a better chance will occur Thursday as a shortwave trough moves across the Western/Central Interior. However, instability today and Thursday is rather meager and thunderstorms will be of the wet variety. The pattern begins to change Thursday as upper ridging builds back in and temps gradually rise above average over most of the Interior. By Friday and Saturday, dry northeast winds will develop and will push temps up into the 70s and min RH values back down into the 20s. Isolated thunderstorms will continue to be a threat Thursday and Friday, as well.

HYDROLOGY. Recent rainfall combined with continued snowmelt across the higher elevations of the White Mountains are causing sharp rises on streams and small rivers draining the White Mountains including the Chena and Salcha Rivers. Some rivers and streams will rise to near bankfull but currently no flooding is expected. River levels will begin falling Wednesday and Thursday.

North Slope Rivers are starting to break up, and with rising freezing levels, expect Brooks Range snowmelt to increase the next several days. Will need to monitor North Slope Rivers closely this week.

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.
