Synopsis for the southern oregon coastal waters - The thermal trough will weaken this morning with north winds diminishing. Calmer conditions are expected this afternoon through tonight. A weak front will result in increasing south winds early Saturday morning, then winds will shift to the west late Saturday morning and afternoon. North winds will increase Sunday with the strongest winds south of cape blanco.

Area Forecast Discussion National Weather Service Medford OR 238 AM PDT Fri Apr 19 2024

DISCUSSION
High pressure will maintain very nice early spring weather across most of SW Oregon and Northern California today.
Some high clouds will drift by at times, but overall, expect mainly sunny skies with a mild afternoon. High temperatures will be largely in the 70s in the valleys west of the Cascades and into the 60s over the East Side. The air mass is quite dry, so humidity this afternoon will drop into the teens and 20s in many areas -- keep the lip balm and skin moisturizer handy. This will also likely prevent any potential pop-up sprinkles/showers from reaching the ground over SE sections of the CWA (though there is a about a 5-10% chance) due to some weak instability over there.
Better chance for this is over the Sierra/NW Nevada.

Dry weather is expected tonight into Saturday as a weak short wave upper ridge swings through. However, a cold front will approach the coast on Saturday. Some rain showers are likely to move into the coastal waters during the morning, and then eventually move onshore Saturday afternoon. Given the preceding dry air mass, it will be difficult for these showers to get very far inland Saturday afternoon/evening. This is evident in the PoP forecast with PoPs not even reaching 15% here in Medford. PoPs will be highest along the coast 18z Sat-00z Sun (50-70%), then lower to 20-40% Saturday evening. Farthest east precip chances (20-40%)
reach the Cascades north of Highway 140. It should be noted that it will get breezy Saturday afternoon/evening in many areas from the WSW, shifting to NW as the front moves through (peak gusts 25-35 mph).

The front shifts east of the area Saturday night with high pressure building in on Sunday/Monday. Frost/freezing conditions are possible during this period of dry weather during the late nights/early mornings in the valleys west of the Cascades. It will only be nominally cooler on Sunday, with high temperatures closer to normal across NW sections, but remaining at least a few degrees above normal elsewhere. Monday will warm up substantially (up 5-10 F over Sunday). Another thermal trough will strengthen in NorCal resulting in another round of N-NE winds late Sunday through Monday. This should even bring the milder weather to portions of the SW coast (Brookings).

The next chance at precip won't come until Tuesday of next week.
Some guidance is showing the upper trough offshore staying well to our north and west with a bit of a moisture surge from the south.
This could cause some showers (thunder?) in parts of NorCal and maybe from the Cascades eastward Tuesday afternoon/evening. Models aren't too bullish on this just yet with NBM PoPs only peaking up around 20%. The upper trough should send a cold front onshore at midweek with a bit of a cool down and a chance of showers.

AVIATION
Other than some high clouds at times and a slight uptick in diurnal breezes this afternoon, VFR will prevail area wide through the next 24 hours. Coastal areas won't be nearly as gusty as yesterday. -Spilde



MARINE
Updated 200 AM Friday, April 19, 2024...A weakening thermal trough will maintain steep, hazardous seas through early this morning. Steep seas will shift to beyond 10 NM from shore and south of Cape Blanco by late morning, then subside below small craft advisory levels this afternoon. Conditions improve tonight with relatively light winds and low seas into Saturday, though a weak cold front will move through on Saturday with some rain. Gusty north winds and steep seas are expected to return later in the weekend with possible gales and very steep, hazardous seas south of Cape Blanco late Sunday into Monday. -Spilde
