What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Juneau, AK wrote its last area forecast discussion before this small craft advisory went out at Aug 14, 3:00 PM AKDT, 30 minutes earlier.
Area forecast discussion, Aug 14, 3:00 PM AKDT, 30 minutes before
Southeast Alaska Forecast Discussion National Weather Service Juneau AK 300 PM AKDT Sat Aug 14 2021 .SHORT TERM.../Through Monday night/ The short term is much quieter than it has been over the past few days. While the chance for rain increases tonight, Southeast Alaska will get a well deserved break from the rain and active weather Sunday and Monday. Aloft, an upper low tracks SE through the gulf tonight and then off into BC Sunday. A jet streak rounds the base of the trough as it passes overhead which helps spawn a weak surface low in the SE gulf tonight. The surface low moves NE into the Southern Panhandle early Sunday morning increasing wind speeds and the chance for rain during that timeframe. Current satellite and radar imagery clearly depict the wave and an associated stream of clouds and moisture aimed at the Panhandle. Ensembles show a healthy plume of moisture associated with this system with IVT values upwards of 500+ kg/m/s. Widespread large scale ascent from the left exit region of a 90+ kt jet streak combined with an approaching surface wave and copious amounts of moisture will lead to heavy rainfall rates across the Southern Panhandle tonight. Highest totals expected across the south where 0.75 to 1.25 inches could fall through Sunday morning. Amounts diminish further north away from the best dynamics with 0.10 to 0.50 expected for the northern half of the region. A drying trend begins late Sunday morning and lasts through Tuesday morning as slight ridging builds in the gulf, giving the Panhandle a well deserved break from the wet weather. With cold air advection moving in aloft, there is quite a bit of unstable air over the gulf. Numerous lightning strikes have been detected associated with a group of showers on the backside of the approaching system in the central gulf. There is the potential for continued lightning across the SE Gulf and possibly portions of the Outer Coast later this evening. Currently think the lightning activity will diminish before reaching the coast; however this will need to be monitored closely. The main wind issues in the short term will be tonight through Sunday morning as the weak surface low pushes into the Southern Panhandle. Expect small craft conditions to develop after midnight across the far SE Gulf and southern Clarence strait. Southerly winds will increase ahead of the low then quickly shift to the west Sunday morning as the low passes by. The abrupt wind shift may cause localized areas of higher erratic wind speeds and directions across the south. Wind speeds diminish during the day on Sunday. Persistent westerly flow continues through early next week; however the pressure gradient over the panhandle remains weak leading to light winds through the Inner Channels with afternoon sea breezes for the rest of the period. Overall confidence remains high through the short term with the overall pattern. Lower confidence regarding the lightning potential near the Outer Coast tonight. .LONG TERM.../ Monday to Saturday, as of 10 PM Friday / Ridging will slowly rebuild through much of the Monday through Tuesday timeframe over SE AK. In the lower levels of the troposphere, this will help cut off the supply of moisture responsible for the lingering chances of rain in some parts of the area. Consequently, expect that the panhandle will see an opportunity to dry out, especially in the southern half of the panhandle. Some offshore flow will even yield breaks in the cloud cover for the area. Although a lingering chance of some showers will remain for the northern half of the panhandle, think that this might still be a little bit more bold than strictly necessary. Unfortunately, the return of more pleasant weather will be short- lived, as a system races up from the Alaska Peninsula into the area. Though the operational runs are not yet marching in full lockstep, the ensembles have broadly come into better agreement that the second half of Tuesday onwards will see the return of rain to SE Alaska. This system looks likely to have a reasonable plume of moisture accompanying it, and so anticipate that it will bring a respectable amount of rain to SE AK. However, while it does look like the plume of moisture extends through a deep column of the atmosphere, it does not look like it will stay over one particular part of the region for an extended period of time at this point in the forecast. Consequently, flooding concerns are anticipated to be on the low side, although this will be closely monitored in the future should conditions change. After Wednesday, forecast confidence rapidly decreases as diverging solutions make it increasingly difficult to differentiate any definitive signal one way or another. && .HYDROLOGY...The Situk near Yakutat crested around 72.4 ft around 3:45am AKDT Friday, which was solidly above minor flood stage of 71.5 ft. It has since fallen to 71 ft, so the Flood Advisory was cancelled at 4:30am AKDT Saturday. The Taiya near Skagway crested around 19.2 ft around 2:00pm Friday and remains above moderate flood stage (17ft) at 17.2 ft, but it is dropping. A Flood Warning is in effect for the Taiya until 1pm AKDT Saturday. The Mendenhall Lake near Juneau continues to rise. It currently is at 11.53 ft, which ties for the 3rd highest crest, and it is still rising at about 0.02 ft per hour, with a current forecast crest of 11.6. A Flood Warning is in effect for the Mendenhall Lake until 4pm AKDT Saturday. Other Juneau area streams have receded substantially, with Auke Lake, Montana Creek, and Jordan Creek all below flood stage. The Flood Advisory has been allowed to expire for those areas Saturday morning. && .AJK WATCHES/WARNINGS/ADVISORIES... PUBLIC...Areal Flood Warning until 4 PM AKDT this afternoon for AKZ025.
