Another Warm Day, Then A Cooldown
Temperatures will cool slightly today but still can be hot inland. A strong ridge to our north weakens and moves east. A cut-off low will migrate north, passing us by to the west throughout the day. The interaction between these two features will switch our flow to the south. Southerly flow is typically warm, so highs will remain above normal! However, they’ll just be a bit cooler than Monday. South-facing coastal areas will also see a stronger sea breeze and a better chance at fog/low clouds—so expect a more significant cool-down in these areas. The low will get absorbed into a passing trough on Wednesday, lowering the pressure over our area and allowing for a deeper marine layer. This will translate to much cooler temperatures and sturdy low cloud cover on the coast.
AIR QUALITY: Good
Today: Slightly cooler overall, but still warm for this time of year with coastal highs ranging from the mid 60s to upper 70s and inland areas ranging from mid 80s to upper 90s. Patchy fog on the coast but sunny elsewhere. Windy up valleys late in the day.
Overnight: Increasing clouds, patchy fog through daybreak with lows in the low to upper 50s.
Wednesday: Remaining mostly cloudy on the coast with highs in the 60s. Mostly sunny inland with highs in the 70s to low 90s.
Extended: We’ll be in for a bit of a temperature roller coaster from mid-week through the weekend as we remain sandwiched in between weather features. The result could be large temperature swings but also low confidence in the forecast. Right now, it looks like most areas will warm back up through Friday, then cool down on Saturday before warming again Sunday/Monday.
