    - Record warmth midweek for Alturas and Klamath Falls
    - Brookings may approach 70 degrees on Wednesday

Further Details:

The forecast turns largely dry the upcoming week with above normal
temperatures. In fact, high temperature records may be met at
Alturas and Klamath Falls midweek. Records are 65 (Feb 4th) and 64
(Feb 5th) for Alturas. Record is 59 for Klamath Falls on Feb 5th.
Each of these days we are forecasting high temperatures within a
degree or two of these records.

A Rex Block (high pressure on the poleward side of a closed low)
sets up at 500mb over the west coast starting tomorrow. This will
keep the pattern stagnant through much of next week. The high of
this Rex Block will be centered over the forecast area through
middle parts of the week which will help aid our above normal
temperatures for this time of year. This pattern does appear to
break down Thursday into Friday as a closed low develops over the
Pacific and enter the PacNW. This will bring our next chance at
precipitation starting Saturday morning. A lot will depend on the
strength of the high as this low could get pushed to the north. At
this time, we are not seeing any noteworthy impacts from rainfall,
but we will need to keep an eye on snow levels and wind speeds.
Currently, the probability for 6.0" of snowfall in 24hrs is around
40% through Sunday night for a small area around Crater Lake.
Otherwise, light snowfall possible at similar elevations. Again, at
this time, we are not expecting widespread hazardous weather.

.AVIATION (18Z TAFs)...

VFR conditions are expected today with generally clear skies and
light wind speeds across the area. Tonight we are anticipating
some valleys to experience fog and low clouds in addition to
coastal areas. However, there wasn`t enough confidence to include
KMFR in any categorical changes, but we may need to reconsider
this in subsequent TAFs if probabilities increase.

.MARINE...Updated 200 PM PST Monday, February 2, 2026...Steep
west seas will persist into tonight, then lower below advisory
criteria for a brief time on Tuesday. Steep seas are likely to
return Wednesday as another building west swell arrives and
combines with a persistent southwest swell. These steep seas may
continue through Friday. High pressure will maintain dry
conditions through Friday. Then a front may move into the area and
bring rain along with a potential for steep west-southwest seas
on the weekend.
