Fxak67 pajk 211414 afdajk southeast alaska forecast discussion national weather service juneau ak 614 am akdt Wed aug 21 2019 Synopsis A gale force low over the north shore of haida gwaii tracks NE and moves ashore around portland canal late this morning. Low pressure then resides over western canada this afternoon and this evening as a weak ridge of high pressure builds over the gulf and panhandle. A new gale force low emerges in the central gulf Thu morning as the ridge migrates to canada. Short term The gale force low took a more southerly course across northern haida gwaii overnight, thus avoiding the worst possible wind impacts. While there were some strong wind gusts, the worst of the winds remained to the south over haida gwaii, first with southeasterlies and this morning with westerlies behind the system. The low will then make landfall around the mouth of portland canal. Perhaps the main impacts for this storm was the copious rainfall. The southern and south-central panhandle received 2 to 6 inches of rainfall, much needed to make up for the drought deficits. Ketchikan even set a new record precipitation total for the date of august 20th. The 4.85 inches was the most the city has received on a single day since february of 2016. While we are certain it was a potentially difficult day to endure if outdoors, it was badly needed. Petersburg, craig, klawock, and wrangell also received beneficial rains. Showers coverage will essentially shrink to the coast mountains and far south by afternoon. Places to the north like juneau barely received a trace, and gustavus and yakutat both fell into the 30s due to clear skies and a much drier air mass. A weak forerunner system arrives from the gulf tonight and applies enough forcing to enhance shower activity late tonight into early Thursday. However the next big system we watch will be a new gale force low entering the central gulf Thursday. There is still model spread on this feature, but largely our previous forecast differed little from the cluster of solutions, so changes were not needed. While steady rainfall spreads across southeast Thursday and Thursday night, we do not anticipate it will produce anywhere near what Tuesday's system brought. We additionally cooled temperatures across the board on Thursday. Breezy conditions will likely occur along the coast and through many of the inner channels. Forecast confidence is generally good. High res models like the hrrr and the namnest aided re-positioning of the low this morning. Long term Friday through Wednesday night as of 10 pm Tuesday active zonal pacific jet will continue just to the south

of the panhandle through Saturday. In general this means the continuation of a general onshore flow pattern and periods of showery weather. As usual in zonal flow, forecast guidance is having trouble nailing down individual shortwave features, but overall a damp forecast through the long term period. There are some indications early next week of upper ridging beginning to develop over the eastern npac. This would tend to be a pattern that would direct more subtropical moisture northward and into the gulf of alaska but exactly when and where this sets up is still in question. Very little in the way of change was made to the forecast as the inherited forecast represented the above pattern well. Temperatures were cooled slightly into the early part of the weekend to account for more cloud cover and rainfall. Potential for some warming early next week as the pacific ridge begins to assert itself. Forecast confidence is high in the general pattern but as usual, low on the details. Aviation While southern airports demanded the most attention with lower ceilings due to the approaching low, improvement has already begun. But due to excess moisture around there is still some chances of periodic very low conditions in fog. Also, some wind sheer has been added over the far south up to sitka. Meanwhile, northern sites are much more simple due to much less impactful weather. Just as eilings gradually improve over the south today, some will lower again tonight to MVFR. Marine The only hazards are confined to marine waters over the far south. A brief small craft advisory early this morning remains for clarence strait, and strong northwesterlies on the back side of the low remain in zones 41 and 42. These will quickly diminish but high seas should linger in zone 41 through tonight. As the low lifts inland into canada, a wind shift to southerly looks to occur in the north and north central inner channels. Hydrology Several southern area streams responded to the 2 to 5 inches of rainfall that fell over the area the last couple of days. But none reached action stage. The heavier rainfall rates have ended across the panhandle, and so rivers and creeks have already begun to respond by falling. Climate We had two records yesterday, august 20. Yakutat dipped to 33 degrees which broke the old record of 35 from 1986. And drought-plagued ketchikan just barely broke a 90 year old daily precipitation record. The 4.85 inches of rainfall broke the old record of 4.84 from 1929. Certainly good news for the far southern panhandle. Ajk watches warnings advisories Public... None. Marine...
