Another scorcher on the coast but sea breeze finally kicked in (desert thermal trough shifted west caused by offshore flow) - desert goes to coast

Classic example of weak offshore flow, preventing the air conditioner Seabreeze from penetrating inland with huge temperature differences of almost 20° from 85F and much higher humidity at main airports near the immediate coast to 105F and very dry a few miles inland

Upper low is sharply cutting SoCal and working on the western edge of tropical moisture from Sunday’s surge, reminds me of what happen well ahead of TC Rosa late September 2018

Isolated thunderstorms across southern Sierra Nevada produce small hail (hard ice) and snow pellets (soft) directly under the upper low center

Sometimes you hear - only if the water was 80°, the hurricane would move towards it - but in reality, the steering flow of the atmosphere such as a Pacific weather system is what controls the track and movement as you can see TC Polo getting picked up on Monday

First surge of tropical remnant moisture moving into California ahead of the incoming Pacific upper trough and backside of the weakening upper ridge - precipitation - rain - another surge for early September

Before El Niño formed we had a major marine heat wave in place (warmer than average sea surface temperatures seen in red on satellite) in the east Pacific- now they are combining #elnino but not everything is El Niño

Alex Tardy - Weather Echo @skiwxman.bsky.social · 21/07/2026

And so it #heatwave continues and then building across the southwest US for rest of July youtu.be/oo_flY8sJ0I?is…

The first significant #monsoon surge made it all the way into Southern Canada, and even wrapped into the Pacific upper low, which is common in the summer - watch atmospheric moisture feeds across the West and see the new surge entering Southern California on satellite July 12-17

Another large closed upper low for significant precipitation in California and feet of Sierra Nevada snow next week

Alex Tardy - Weather Echo @skiwxman.bsky.social · 17/04/2026

More precipitation next week! Storm 3. Starting Monday on North Coast and spreading inland Tuesday. Closed upper low and this could be followed by yet another in late April - trying to make up for March with 70 inches this month at Palisades

Alex Tardy - Weather Echo @skiwxman.bsky.social · 09/04/2026

Quite amazing how consolidated the storm is becoming in NWP with a very similar path and target of Northern California and the Sierra Nevada with potential for much greater snowfall (colder, lower snow levels and storm slows) than the April 1 storm - high wind weatherecho.com/f/another-ap...

On track for heavy rain and large snowfall in feet and low snow levels (cold storm) through February 19 - then next storm Feb 23-25

Alex Tardy - Weather Echo @skiwxman.bsky.social · 11/02/2026

The precipitation has arrived in California and a lot more to come - several feet of snow and inches of rain - with a series of progressively colder storm systems from the Gulf of Alaska youtu.be/5JyYbo1J2wI?...

Alex Tardy - Weather Echo @skiwxman.bsky.social · 10/02/2026

Simply huge precipitation potential with cold upper lows slowing moving though especially Feb 14-20 - monster snowfall amounts of 4-8 feet Sierra Nevada but even 1-4 feet SoCal - not to mention heavy rain!
