Southeast Alaska Forecast Discussion National Weather Service Juneau AK 237 PM AKDT Mon Mar 18 2024
SHORT TERM
/Through Tuesday night/...Some left over showers this evening, then drying conditions beginning Tuesday will set the stage for the remainder of the week. Three things to watch will be fog, outflow winds, and overnight lows.
It never takes much to produce fog in Southeast Alaska, and that is all the more the case when showers end and cloud cover begins to thin. Look for scattered cloud cover expanding from north to south through the night. By mid morning Tuesday, most of Southeast Alaska should be enjoying a mostly sunny day. As the cloud cover diminishes tonight, the fog will form as overnight lows fall to the dewpoint temperature. Am expecting the fog to dissipate by mid morning, then return again Tuesday night but not quite as extensively.
Regarding overnight lows tonight, model guidance from every source looked at today suggests significantly cooler temps than last night. This would be fine apart from the fact that those temps are much cooler than the current dewpoint temperatures.
Having temperatures fall significantly below the afternoon dewpoint values is a log shot forecast and, in this case, represents the lowest confidence portion of this short term forecast.
As a broad and weak area of low pressure over the southeast Gulf of Alaska drifts southeast and merges with low pressure over the PACNORWEST, an inverted trough will form over the Panhandle. This will allow for northerly outflow winds to set up over Southeast Alaska beginning Tuesday. Forecast winds are not anywhere near some of the stronger winter outflow winds the region has experienced this past Winter, but will still be strong enough to generate max small craft conditions over Lynn Canal, gusty conditions in downtown Juneau, and outflow wind plumes out of the usual places - Icy Bay, Cross Sound, White Pass, Taku Inlet, and perhaps even the Stikine River Delta.
LONG TERM
For the start of the long term, high pressure looks to remain in control of the weather over SE AK. With this pattern set in place, outflow winds will be over the area with clear skies. Temperatures during the overnight hours are expected to cool due to radiational cooling. With the clear conditions during the day, temperatures will warm as the hours of daylight continue to slowly increase allowing for more daytime heating. Overall, things are expected to remain calm and rather dry for the long term. Currently guidance shows the area of high pressure slowly breaking down and shifting east by Monday but confidence in this is still lower.
AVIATION
We are seeing an improvement in ceilings today with most locations reporting MVFR to VFR and a few passing showers with brief MVFR around Yakutat, along the central outer coast, as well as the southern areas. The next thing to watch for as we loose the stratocumulus at 025-045 AGL, we expect to see areas of fog form up tonight and, for now, have a period of IFR/LIFR several sites 10-19Z. Expect the fog to burn off by 20Z most locations. Otherwise tomorrow afternoon we are expecting generally VFR area wide with light northerly flow.
MARINE
Combined seas in the northeast Gulf are hovering right around 8 feet, which is the threshold for small craft conditions due to seas. Have opted to not include small craft advisories for the northeast Gulf coastal marine zones betting on a subsiding sea state. By tomorrow afternoon, a long period swell may result in 8 ft seas offshore between Cape Edgecumbe and Cape Decision late tomorrow afternoon. Also tomorrow afternoon, northerly winds of 25 kts or more are expected over lynn Canal as outflow conditions set up. Winds over the canal are expected to increase through Tuesday night. Elsewhere, winds 20 kts or less and seas 7 ft or less on the outside and 4 ft or less on the inside.
