New SYNOPSIS, SHORT TERM, LONG TERM

SYNOPSIS
Issued at 105 PM PDT Sat May 4 2024

Rainfall ending this afternoon from north to south. Some clearing this afternoon with light isolated showers tonight. Mostly clear Sunday with a warming trend on track for the upcoming week.

SHORT TERM
(This evening through Sunday)
Issued at 105 PM PDT Sat May 4 2024

Rain unfolding as expected as of midday with the heaviest having pushed through with the initial cold front this morning. Areas from the Bay Area southward will continue to see light-to-moderate rain into the this afternoon, but as of writing, observed amounts are generally 0.6-1.5" with the highest amounts being in the coastal ranges. Clearing will occur rather abruptly through this afternoon and evening from north to south with visible satellite showing a sharp cutoff in overcast cloud cover on the back side of the front. We can expect some degree of isolated showers behind the front tonight, but instability appears lacking overall which would hinder the coverage and intensity of any post-frontal showers a bit. No lightning strikes thus far neither, given the fairly suppressed nature of the post-frontal convection. Can't rule out a strike or two as we go into tonight, but it's a very small chance.

Sunday looks to be clear and pleasant, despite chilly temps with highs in the upper 50s to lower 60s across the region.

LONG TERM
(Sunday night through next Friday)
Issued at 105 PM PDT Sat May 4 2024

The next week is on track to be clear and dry with temps steadily increasing each day into late week. Ridging dominates as we settle into a more seasonal pattern. By Friday, expect temperatures 5-10 degrees above normal...mid-to-upper 80s for inland valleys, upper 70s to lower 80s elsewhere, and upper 60s to lower 70s along the coast. Friday may be a potential day to highlight an elevated risk of heat-related illness for sensitive groups in urban areas of the South Bay and interior East Bay valleys. Stay tuned to the forecast as this will likely be, yet again, among the warmest temps some have seen this year so far.
