Southeast Alaska Forecast Discussion National Weather Service Juneau AK 606 AM AKDT Fri Jul 10 2020

SHORT TERM. /Through Saturday night/ . Rain will transition to showers as the front currently draped over Southeast Alaska weakens. The parent low, currently over the south-central Gulf. will track east, then northeast and weaken as it approaches the Dixon Entrance on Saturday. Small craft southeasterlies over Clarence Strait will diminish to 15 kts by late tonight, then increase to 20 kts on Saturday. Southerly 20 kt winds are also forecast over northern Lynn Canal for Saturday. Elsewhere on the inside . 15 kts or less.

Cloud cover will limit daytime highs once again to the upper 50s or possibly the lower 50s in some spots. Overnight lows will only get down to the lower 50s or upper 40s for the same reason - the clouds.

All in all, a very quiet short term forecast. Overall forecast confidence is average to above average. I'm going to bed.

LONG TERM. /Sunday through next Thursday/ As of 19pm Thursday. A weak/short-lived ridge will form early Sunday behind the low pressure system that caused all our weather the previous couple days. This will allow for more breaks in the showers. But upper level flow backs through the day and becomes more zonal and westerly, pushing the surface ridge inland and likely keeping most areas mostly cloudy.

A new system moves across the gulf from the west on Monday, but models differ quite a bit on timing of that. The Canadian is the fastest, the GFS is the slowest and furthest north, while the 14/12z ECMWF right in the middle for timing but weaker and about as far south as the Canadian. The consensus is for rain to move in late Monday night and Tuesday having the highest POP of the week. But if the Canadian is right then it could be early evening Monday for the south and if the GFS is right then most of the rain focus would be on the northern gulf coast Tuesday morning. Opted for a compromise between these model solutions by blending in their previous runs that were in slightly better agreement, placing the likely over the southern 2/3 of the region from Elfin Cover to Ketchikan. Due to expected cloudy/rainy weather on Tues into Wed, went below guidance for high temperatures and may need to lower them more into the 50s.

Once the low weakens and moves through on Wednesday, there are signs of more ridging for the end of the week, but with a lot of uncertainty. Model snow levels and temperatures do show an increasing trend however.

It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
