Area Forecast Discussion National Weather Service Medford OR 851 PM PDT Mon Sep 27 2021

DISCUSSION. Rainfall associated with the cold frontal passage should exit the east side around 2 AM tonight. The more substantial rainfall is just now making it to Lake and Modoc counties. Values of a tenth to half an inch have been common elsewhere, except an inch to as much 4.63 inches (at Red Mound in the Curry County mountains) at the coast, and an inch or a little more in Douglas County.

The forecast has been updated to adjust sky cover in the short term through Friday, generally to increase cloud cover on the west side through Tuesday evening. Also, to more broadly increase cloud cover, and add a slight chance of light showers to our northern tier with a shortwave trough passage late Thursday night into Friday morning.

A freeze warning remains in effect for Wednesday morning for much of our northern California and south central Oregon area, with the coldest temperatures of the season so far, and coldest of this week expected.

AVIATION. 28/00Z TAFs . Along the coast . Areas of MVFR cigs/vis and local IFR conditions are expected to continue along the coast through early Tuesday morning. Then conditions will improve to VFR with local MVFR cigs late Tuesday morning and afternoon.

Inland . Mountain obscuration, showers, and areas of MVFR will persist over the area through early Tuesday morning. Shower activity will gradually decrease during the day Tuesday. Conditions will lift to VFR with local MVFR and areas of mountain obscurations late Tuesday morning and Tuesday afternoon. -CC

MARINE. Updated 800 PM PDT Monday 27 September 2021 . Conditions hazardous to small craft are expected to persist for all areas through at least Tuesday night as steep west-northwest swell builds in. Swell begins to subside Tuesday afternoon and this trend continues into Wednesday. Generally light south winds will continue over the waters through Wednesday. Another front will near the area on Wednesday morning, and south winds will increase some north of Cape Blanco. -Keene/CC

PREV DISCUSSION. /Issued 248 PM PDT Mon Sep 27 2021/

DISCUSSION . After periods of rain this morning, the front is beginning to pus onshore this afternoon. The main belt of rain, as of this writing, lies between the Cascades and the coastline, and is steadily making its way to the east. Rainfall amounts so far today have been healthy, especially with this main band, and nearly all of the forecast area is expected to receive a good wetting rain by late tonight, or early tomorrow morning for the far eastern portions of the area. Post-frontal showers are expected tonight and much of tomorrow, with additional rainfall amounts likely, especially along and west of the Cascades, were onshore moisture and upslope factors will be stronger. Precipitation should come to an end for most areas by Tuesday afternoon, but may linger along the coats and over the eastern Umpqua Basin and Douglas County Foothills into the late evening.

Snow levels behind the front are forecast to lower to between 5000 and 5500 feet, above all but the highest passes in the region. As the bulk of moisture will come as showers by this time, snow accumulations on the higher peaks and ridges should only amount to an inch or two, although higher amounts are possible in location such as Crater Lake Rim.

The coldest air of the season so far will arrive behind the front. There should be enough clouds, residual showers, and breezes early Tuesday morning to prevent temperatures from falling below freezing in the valleys of the East Side, but if clouds clear sooner than expected, an hour or so of frosty or below-freezing temperatures is possible. Tuesday night into Wednesday morning, however, clear skies and calm winds should allow plenty of radiational cooling, and temperatures should drop into the 20s, or even as low as the lower 20s for the East Side valleys, as well as in Modoc and northeastern Sikiyou counties, and the Scott Valley in western Siskiyou County. A Freeze Warning has been issued, in effect late Tuesday night through Wedensday morning, to cover what is likely to be the end of the growing season for those areas.

Ridging will begin building into the forecast area Wednesday and Thursday, with temperatures warming behind the passage of a dry warm front during the day Wednesday. A weak trough and cold front will follow Thursday night into Friday morning, but will pass mostly to our north, keeping the vast majority of the rain away from our region, although a stray shower or two is possible along the coast or in the Umpqua Basin. Ridging then returns for the remainder of the forecast period, with dry conditions and near or slightly above normal temperatures forecast through the weekend and into early next week. -BPN

FIRE WEATHER . Updated 300 PM PDT Monday 27 September 2021 . Gusty winds continue ahead of the front with some areas in the eastern portions of FWZ 285 coming close to red flag warning criteria. However, humidities are expected to be too high for red flag as the front edges closer. Otherwise, the only fire weather concern will be the dry stretch through the next 10 days or so. Given the time of season and the chance of more rain coming beyond day 10, the concern is pretty low.
