AREA FORECAST DISCUSSION National Weather Service Eureka CA 317 PM PDT Sun Apr 28 2024
SYNOPSIS
High pressure continues to build offshore as a cold upper trough digs into the PNW. Very light precipitation in Del Norte, coastal stratus and below normal temperatures expected through mid week. Offshore flow and high pressure will promote warming and drying in the interior late week.
DISCUSSION
Light stratiform drizzle has dissipated across the north coast this afternoon following a weak cold frontal boundary.
Scattered cloud cover and broken sunshine should enhance coastal temps slightly, although breezy NW winds will ensure highs remain in the upper 50s. Low level moisture trapped beneath encroaching high pressure subsidence will return low stratus to coastal Del Norte and Humboldt counties this evening into Monday morning.
Meanwhile, conditions across the interior will be much drier beneath mostly clear skies. After valley high temperatures in the mid to upper 60s today, a frost advisory will go into effect beginning at 3 AM Monday morning as radiational cooling and relatively weak N winds send temperatures plummeting into the upper 20's and low 30's. HRRR indicates a 50 to 75 % probability of <35 degrees early Monday morning in lower elevations of northeastern Mendocino and Trinity counties.
Synoptic scale zonal flow will soon be interrupted by a cold upper low descending into the PNW Monday morning, bringing another few rounds of light rainfall to northern Humboldt and Del Norte counties Monday and Tuesday. Once again, limited QPF will prevent significant accumulations - additional rainfall is unlikely to exceed 0.05 inches on the far northern Del Norte coast. Otherwise, coastal areas will see a similar pattern each morning of low ceilings that scatter out with daytime heating. Cool NW flow will continue to dampen temperatures along the coast and in the interior, with valley temperatures only likely to reach the low 60's on Monday and Tuesday. NBM continues to highlight Tuesday and Wednesday morning with anomalously cold morning temperatures. A freeze watch has been issued for Tuesday morning for Trinity County with 50-75% NBM probabilities of <32 degrees.
Strong mid to upper-level winds will remain decoupled from the surface layer below 5,000 ft - as a result, HRRR is beginning to align with NBM to indicate that 25-30 mph winds will stay confined the coastal headlands of Cape Mendocino and exposed ridges in southern Humboldt, Mendocino and Lake counties late Tuesday.
As the high pressure ridge continues to build into the PNW, cloud cover is expected to dissipate more reliably along the coast as temperatures increase across the CWA Late Tuesday into Wednesday, gusty northerly winds are expected as the pressure gradient tightens considerably along the coast. Clearing skies and increasing offshore flow early Wednesday will promote widespread warming and drying across the region, especially in the interior. RH values currently forecast to drop to 30% in interior Mendocino, Trinity and Lake Counties. Models are still without consensus on high valley temperatures Thursday and Friday - right now NBM only has >50% probabilities in southern Mendocino and Lake counties. Regardless, an overall warming trend is expected with highs in the 70's.
AVIATION
Ensembles indicate that stratus and the chance of MVFR visibility (50-70%) or lower returns along the coast by the 03Z-05Z time frame along the coast. By 12Z Monday, HRRR ensemble mean indicates light shower potential increases for the coast, especially for KCEC and lasts through 18-21Z, then quickly decreasing stratus for the rest of the afternoon. Ensembles still indicate the diurnal gustiness for KUKI through early evening, and again the afternoon Monday.
MARINE
A couple of persistent northwest swells for the next several days gives us a combined wave height of 6-7 feet today, and near 8 feet Monday, peaking at 10-11 feet by Wednesday. Wind speeds gradually get stronger by mid-week as well. Models are still showing potential for marginal small craft advisory potential for Monday, but will hold off for now as the current forecast is slightly overforecasting the steepness of waves. By mid-week, signals for small craft potential grow stronger, especially in southern waters.
