Updated 230pm Saturday, July 13, 2024...Winds and seas will be at a peak into this evening, but a thermal trough will continue to bring moderate to strong north winds into Monday evening. This includes gales along with very steep, hazardous seas beyond 5 nm south of Port Orford through Sunday evening. Very steep wind driven seas up to 13 feet will persist in roughly the same area.

Winds and seas will lower some Sunday night into Monday evening, but expect continued gusty north winds and steep seas across much of the waters. Then winds and seas are expected to gradually diminish Tuesday through Thursday. -DW

Fire Weather
...RED FLAG WARNING IN EFFECT UNTIL 8pm THIS EVENING FOR STRONG GUSTY WIND AND LOW RH FOR NORTHERN FIRE WEATHER ZONES 624 AND 625... ...RED FLAG WARNING IN EFFECT UNTIL 11pm PDT SUNDAY FOR LIGHTNING ON DRY FUELS FOR FIRE WEATHER ZONES 284...285..624 AND 625... ...RED FLAG WARNING IN EFFECT FROM 2am TO 11pm PDT SUNDAY FOR LIGHTNING ON DRY FUELS FOR FIRE WEATHER ZONES 280...281...282... AND 621... ...FIRE WEATHER WATCH IN EFFECT FROM SUNDAY EVENING THROUGH MONDAY EVENING FOR LIGHTNING ON DRY FUELS FOR FIRE WEATHER ZONES 280...281...282...284...285...624 AND 625... Hot, breezy, low humidities, and unstable afternoon conditions will persist through this weekend. The focus of today's efforts was to fine tune the thunderstorm forecast for this weekend and to glean any details for the Monday/Tuesday timeframe as well. Strong high pressure will linger over the Great Basin region into next week and a weak low pressure will move northward just offshore of the California coast. This is a pretty classic thunderstorm pattern for this area as the flow turns more southerly and moist unstable air moves into the region.

For today, we expect isolated thunderstorms to be focused over our southeastern zones (284, 285, southern 624 and 625) and this is covered by the current Red Flag Warning (RFW). Storms are already moving into Modoc County this afternoon, so the forecast remains on track for today. Meanwhile, the RFW for FWZs 624 and 625 is actually a combination of critical concerns. Gusty southwest winds have shifted northward today and humidities will remain very low across the northern portions of those zones. So north of a line from roughly Chiloquin to Paisley, we expect critical fire weather conditions due to gusty winds and low RH, while south of there the concern is due to lightning on dry fuels. Though confidence is higher for isolated coverage vs scattered, any lightning in the area right now should be highly efficient fire starters thanks to the recent prolonged stretch of very hot and very dry conditions. Additionally, any storms that develop today into tonight will be high based and have very little to no precipitation with them.

As we head into tonight and Sunday, the potential for thunderstorms shifts westward. It's not out of the question we see some isolated, elevated convection continue Saturday night into Sunday morning, but Sunday afternoon and evening looks like the day for the most coverage of storms as the mid-level moisture field shifts westward. Have upgraded the Fire Weather Watch for FWZ 624, 625, 284, 285, 280 to a Red Flag Warning and have also added FWZs 281, 282 and 621 to the warning. Additionally, to cover the potential for isolated dry thunderstorms for the overnight period, have basically just stretched out the current Red Flag Warning to continue overnight tonight through late Sunday evening. The exception being FWZs 280/281/282/621 where that Red Flag starts at 2 am tonight and carries through late Sunday evening. Storms should trend wetter on Sunday, but will still be a mix of dry and wet storms, with lightning strikes outside of precipitation cores a real possibility and cause for concern.

The focus of today's efforts has largely been on the weekend setup, but it looks like we'll maintain at least isolated thunderstorm chances Monday into Tuesday. There is some uncertainty due to model differences regarding where these chances are focused, which could include west of the Cascades or even nocturnal thunderstorms at some point. We've gone ahead and issued a Fire Weather Watch for late Sunday night through Monday evening where confidence is highest for the continued thunderstorm threat, and this includes FWZs 280/281/282/284/285/624/625.

We'll have to monitor model trends closely as each day passes, but we'll be in a thunderstorm pattern through Tuesday, and subtle shifts in model trends could lead to big changes in the forecast. /BR-y
