New AVIATION, MARINE

SYNOPSIS
Issued at 1238 PM PDT Sat Jun 15 2024

Dry and windy with elevated fire concerns into early next week.
Seasonal temps and quiet weather midweek. Potential warming trend for late next week.

SHORT TERM
(This evening through Sunday)
Issued at 1238 PM PDT Sat Jun 15 2024

Clear skies continue into the evening with drier conditions compared to yesterday evening. N-S gradient continues to strengthen bringing some occasional gusty strong winds, especially over the hills, coastal gaps, and mountain ranges, into the late evening. The winds will mostly have impacts over our marine zones where winds can reach up to 45-55 mph, especially along the Big Sur coast. With this strong gradient and drier air conditions, clouds will remain mixed out going into Sunday, giving us a break from the June-Gloom. With the clear skies, expect a few degrees lower tonight, compared to last night as radiative cooling goes into effect. Minimum temperatures will get down to mid 40s to mid 50s across the region.
As we low pressure system off the Pacific NE move closer inland and sit over Washington and Oregon state on Sunday, expect another day of cooler temperatures. Inland areas are looking to see high 70s to low 80s, with the coastline seeing max temperatures in the 60s. Strong northerly winds will also support cooler temperatures going into Sunday.

LONG TERM
(Sunday night through next Friday)
Issued at 1238 PM PDT Sat Jun 15 2024

As we move into the beginning of the work week, we will start to see that low pressure system gradually dip down even further into our area, allowing for some strong gusty winds to persist Sunday into Monday. This does bring some fire concerns as the minimum relative humidity values are expected to get down to the teens in certain parts of the region. Although there are some areas in our region that bring elevated fire concerns, no RFW have been issued as the overall conditions have not met warning criteria for our area at this moment. Fire conditions will be closely monitored, especially if the north/northeast winds linger and low relative humidity continues beyond Monday afternoon. (See Fire Weather discussion below for more details)

As we move into Tuesday, we will start to see the N-S gradients to gradually decrease as the upper level pattern start to transition into a zonal/weak ridging pattern. This will bring a warming trend starting Thursday with temperatures in the upper 80s and 90s going into the weekend with some chances of triple digit values. CPC and WPC outlooks also show portions of our area for excessive heat with a 50-60% above normal temperatures.

AVIATION
(00Z TAFS)
Issued at 418 PM PDT Sat Jun 15 2024

VFR conditions throughout the region, generally through the TAF period. Model output has some probability of stratus development tonight at the immediate coast and the Monterey Bay region, but confidence is low and strong winds aloft may keep the skies clear through the nighttime. Strong northwest winds will develop through the afternoon and evening with gusts up to 25-35 knots at the terminals. Winds will abate overnight, but remain breezy across the coastal regions, before winds as strong or somewhat stronger than those seen later today develop Sunday afternoon. Marginal LLWS concerns will develop on Sunday evening along the coastal ranges as the surface layer decouples, but confidence is too low to include it in the TAFs.

Vicinity of SFO... VFR through the TAF period. Strong west-northwest winds will build into the evening with gusts up to 35-40 knots.
Winds will abate overnight, but remain breezy and gusty with the intense gusts returning on Sunday afternoon. Marginal LLWS concerns develop on Sunday evening close to the end of the TAF period.

SFO Bridge Approach... Similar to SFO.

Monterey Bay Terminals... Model output shows some probability of IFR ceilings in the region overnight, but confidence is low and the TAFs remain VFR throughout. Strong onshore winds gusting to around 25 knots will develop this afternoon and evening, becoming breezy overnight before resuming Sunday afternoon.

MARINE
(Tonight through next Thursday)
Issued at 418 PM PDT Sat Jun 15 2024

A tight pressure gradient over the waters will continue to allow for strong northwesterly breezes and widespread gale force gusts to persist through the weekend. Significant wave heights will reach 12-17 feet through the weekend before beginning an abating trend Monday. Hazardous conditions will linger into the first half of next week as winds remain strong.

FIRE WEATHER
Issued at 345 AM PDT Sat Jun 14 2024

Elevated Fire Weather Conditions Through The Weekend

*Increasing northerly winds, especially higher terrain *Lowering relative humidity values day and night

Forecast remains on track as northerly flow ramps up across the district. Gusts of 30-50 mph will be more common along the coast, higher terrain, and inland gaps/passes. Have already seen a few isolated inland passes reach close to 60 mph as well. These stronger winds will persist through early Monday. It should be noted that they will not be strong the entire time, more like bursts of stronger winds. The northerly flow has also ushered in much drier air across the region too. 24 hour trends show some locations 40-70% drier than 24 hours ago. While there are a few isolated stations that may "technically" reach Red Flag criteria conditions are not widespread enough to warrant a fire weather zone wide Red Flag warning. Therefore, still best to message elevated fire weather conditions through the weekend.

Regardless, individuals with outdoor activities planned this weekend should be fire weather aware. Be mindful and don't be "that spark".
