SYNOPSIS
Issued at 1243 AM PDT Mon Jun 24 2024

Temperatures near to slightly above seasonal averages with a slight cooldown midweek. Very low chance of elevated convection and associated dry lightning in the southern Central Coast.

SHORT TERM
(Today and tonight)
Issued at 1243 AM PDT Mon Jun 24 2024

Satellite imagery shows generally clear conditions throughout the region, with a patch of stratus along the northern coast of Monterey Bay. The region is generally expected to remain clear through the night, with a moderate confidence that stratus expands across the the Monterey Bay region before clearing in the morning. Low temperatures this morning range from the upper 40s to around 60 in the lower elevations, and up to the low 70s in the higher elevations. High temperatures this morning range from the mid 80s to the upper 90s in the inland valleys, to the 70s across the Bayshore, and the upper 50s to mid 60s along the Pacific coast.

Regarding the potential for elevated convection in the Central Coast later this afternoon and evening: The three ingredients necessary for any convective activity are moisture, instability, and lift. Mid- level moisture is the most certain ingredient, with a plume of moisture migrating northwards with PWAT values up to 1-1.25". For context, if those values were reported at our upper air site at Oakland airport, those precipitable water values would be at or above the 90th percentile value for all observed soundings at this time of year. Instability and lift are more uncertain. The NAM is showing a plume of unstable air coming towards the north as the mid level moisture comes through the area, but the GFS and European models aren't as aggressive with the MUCAPE values. As for lift, even the NAM is not showing any significant source of vertical vorticity in the region, so any activity would have to be topographically forced. At this point, the most likely scenario is that mid-level clouds and virga will come through the region, with dry air under the elevated moist layer limiting the probability that any precipitation reaches the ground. Perhaps a 10-15% probability for convection in the Central Coast, and that might be a little optimistic. The main impact if convection does develop would be the possibility for dry lightning setting off grass and shrub fires, but this is a "low confidence-high impact" type of event at this stage.

LONG TERM
(Tuesday through Sunday)
Issued at 1243 AM PDT Mon Jun 24 2024

The mid-level moisture will remain on Tuesday, with PWAT values increasing to as high as 1.5", and so will the uncertainties regarding instability, lift, and potential convective activity.
Wednesday sees an upper level trough move in which will push the moisture out of our region, and herald a gradual cooling trend in temperatures for the interior regions. By the end of the week, temperatures across the interior will top out at around 90 in the warmest spots, with most of the inland valleys seeing temperatures within the 80s. Towards the beginning of July, model ensemble clusters are indicating a couple of ridges approaching the West Coast, with early indications of a warming trend towards the end of the 7-day forecast.

AVIATION
(12Z TAFS)
Issued at 413 AM PDT Mon Jun 24 2024

The marine layer is approximately 1000 feet deep. Radiative cooling to space (loss of heat) overnight is assisting coastal stratus and fog /LIFR-IFR/ redevelopment. Inland it's a near high confidence VFR forecast. The leading gradient of increasing precipitable water (near 1") is slowly advancing northward over our forecast area from southern California. With a northward progression of mid level water vapor reaching our forecast area, convective parameters for mid level convection will steadily increase today, however 700-500 mb thermal troughing is rather ill-defined today until slightly more structured mid-level upward forcing arrives this afternoon and/or evening. Not enough forecast confidence to place convection in the 12z TAFs. Greater levels of water vapor above the marine layer tonight and predawn Tuesday morning will slow radiative cooling to space which may help limit areal coverage of stratus and fog.

Vicinity of SFO...Moderate to high confidence VFR forecast for the period. Northwest to west wind 5 to 12 knots through this morning, increasing to 14 to 22 knots this afternoon and evening.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...An eddy circulation has developed over the northern Monterey Bay area, with stratus and fog caught up in the circulation. IFR developing at KMRY and KSNS during the morning.
Stratus and fog /LIFR-IFR/ mixing out by late morning. Mid to late afternoon and evening will need to keep an eye to the sky for potential mid level convection, for now thunderstorm(s) not in current TAFs.

MARINE
(Today through Saturday)
Issued at 320 AM PDT Mon Jun 24 2024

Hazardous conditions for small crafts persist across the northern coastal waters through early week. Fresh to strong northwest winds continue over the northern coastal waters. Fresh gusts remain possible over the southern outer waters. Significant wave heights over the northern waters will build to 10-11 feet through today before wave heights abate below 10 feet by Tuesday.

MTR WATCHES/WARNINGS/ADVISORIES
CA...Coastal Flood Advisory until 4 AM PDT early this morning for CAZ506.

PZ...Small Craft Advisory until 9 AM PDT Tuesday for Pt Arena to Pt Reyes 10-60 NM.
