We’re gonna really have to start watching future model runs of what 95E is gonna do in the Eastern Pacific. What makes us even more concerning and interesting is a favorable phase up with a very well defined upper level low right off the central coast of California with 95E entering in the right front quadrant could actually lead to baroclinic dynamical deepening and transition. Should that happen? This would unleash significant rainfall and flooding for Southern California with strong winds as well. A rare tropical storm of landfall is not out of the question. But one thing crucial here is in future model runs is where the cut off low develops in relation of when 95E enters into the picture. The timing is everything here. if the upper level low is further west then 95E could slip Westward and travel up the California coast compared to a scenario where the upper level low is much closer to the coast allowing 95E to impact the desert Southwest instead.

I’m surprised no storm chasers or meteorologists in this community are taking about how a huge nail to our community is occurring. The Trump Admin is going forward removing the supercomputer at NCAR. This supercomputer is where we develop research for weather models, physics cores, climate dynamics, MPAS, ensembles, WRF and improving the current models we use daily. Taking this away would deprecate the meteorological community significantly.

Could FireGuard be next?
🚨The U.S. Department of Defense will stop transmitting microwave satellite data vital for hurricane forecasts by June 30, 2025, catching forecasters off guard. Experts warn the move will reduce forecast accuracy, risking delayed warnings and public safety during peak hurricane season. open.substack.com/pub/theint…

How are we going to fill Incident Meteorologist positions this year. There will be catastrophic outcomes without this vital service.

The same applies to those that forecast Santa Ana winds 10 days out…irresponsibly

🔴⚠️🔥🇺🇸 axZoom into the burning area of #MountainFire, the SWIR bands of #Sentinel2 on Nov.6 show the #wildfire close to #SantaPaula and especially to #Camarillo which is also on the path of the heavy smoke and it has increased to 10400acres. #CaWx #California #climatemergency
🔴⚠️🔥🇺🇸This is the first image of #mountainFire which has started in the #Ventura County rapidly growing to 10000 acres The brush fire boosted by Santa Ana winds is causing evacuations with injured and structures already destroyed. Here the #Sentinel2📸of Nov.6 #California

All nine Republican senators running for reelection just voted against the Right to IVF Act: John Barrasso Marsha Blackburn Kevin Cramer Ted Cruz Deb Fischer Josh Hawley Pete Ricketts Rick Scott Roger Wicker (JD Vance missed today's vote) So much for the party of "freedom."
