Southeast Alaska Forecast Discussion National Weather Service Juneau AK 251 PM AKDT Sat May 30 2020

SHORT TERM. With a decaying low situated over the central gulf and moist southeast flow directed across Southeast Alaska, our region has endured mostly cloudy skies with a few showers passing along the coast and the Coast Mountains. With much warmer air along with much the same upper level dynamics to our east, moist and unstable air has sparked a few thunderstorms this Saturday afternoon. But none look to cross the international border.

Successive disturbances rotating around the main low center, at first tonight, then a stronger one associated with a front on Sunday, in turn progressively yield more expansive shower activity across our region. All told, precipitation amounts should be light and amount to no more than a tenth to one-half inch Monday. High temperatures should also fall a bit Sunday as they settle back into the 50s region-wide. While south winds do increase a bit tonight through Sunday through the Inner Channels, we hold off on small craft advisories until a much stronger system arrives to welcome June.

The responsible gulf low opens into a trough by late Sunday and clears the northern Panhandle by Monday morning. Mean flow becomes much more southerly at this point at both mid and low levels. Therefore, we expect showers to become more widespread, especially across the north where orographics are maximized.

A new gale force system arrives with North Pacific jet support on its heels for Tuesday. This system carries with it warmer air and more subtropical moisture that re-stabilizes the atmosphere Tuesday. Therefore, we expect precipitation to quickly become steadier rains. From midnight Monday morning to midnight Tuesday morning we expect rainfall amounts of around a half to one inch, and there could be some periods of moderate rainfall over the south. While flooding is not expected, area rivers, creeks, and lakes should respond with rises from Sunday into Monday. With greater rain rates come lower high temperatures. In fact, highs will barely hit the lower 50s in most locations, and we have even held temperatures back into the high 40s on Prince of Wales Island where some of the heaviest amounts will fall. Winds will also present concerns. They rise quickly across the gulf Monday morning to 35 to 40 kt gales by Monday afternoon. We lowered wind speeds through the Inner Channels ahead of presumed more stable and stratified winds. But we do fully expect 25 to 30 kt winds to develop through the southern Inner Channels. Baranof and Prince of Wales Islands, the southern Inner Channels, and quite possibly the Upper Lynn Canal region could experience gusty conditions along with a chilly rain.

Forecast confidence is generally high, as there has been consistent synoptic guidance with these systems for several days. New guidance provided some subtle shifts in the forecast.

LONG TERM. /Tuesday through Saturday/ With onshore flow firmly entrenched, precip will begin to become more organized and robust over the panhandle through Tuesday as a trough associated with the low moves through the region. This should result in some wetting rain, however highest totals currently look to be in the south around Hydaburg and Ketchikan, with heaviest rain seeming likely Tuesday morning. These projections are based on the current forecast and will very much be scrutinized several more times for future forecast packages as the event draws closer. After the trough passes through, onshore flow will remain in place for most of the week which will continue to promote cloudy skies and chances for precip across the panhandle. Near the end of the week, some model guidance is hinting at a break from the rainy conditions, particularly further north with the low breaking up. However, don't go planning a picnic yet as at that far out, enough discrepancy between the models exists that confidence is very low.

Forecaster's preference of models was a blend of the ECMWF/GFS for the Mon-Tue event. Afterwards, changes were minimal and were based mainly on WPC guidance. Forecast confidence in that a decent rain and coastal wind event is likely for the Mon-Tue time frame is increasing. Beyond that point, forecast certainty drops off precipitously.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
