Another shot of Sierra snowfall on the decent into #RNO.

Approach to RNO with #VisitLakeTahoe and #OSS2023 on the agenda!

3 weeks of California storms visualized in 30sec. ~30 trillion gallons of water! I shared a few points about the event here: linkedin.com/posts/ahmadali Data: MRMS (by NOAA) on AWS S3 (hourly, 1km spatial resolution) Tools: Python (mainly xarray & cartopy)

A winter storm moving across the Central Plains today will spread heavy snow into the Upper Midwest and Great Lakes tonight and Thursday, and into the Northeast Thursday night and Friday. Heavy snowfall rates and some icing will create dangerous travel in many areas.

HOT OFF THE PRESSES: Updated total precipitation map for California for a period of 22 days stretching from December 26 to January 17. The AVERAGE over the ENTIRE STATE in that time frame was 11.47 inches, with several locations in central California setting 3-week records.

UPDATED snow total map for California for a period of 22 days stretching from December 26 to January 17. The gridded analysis estimates from nohrsc.noaa.gov/snowfall and some observations indicate upwards of 15 FEET of snow fell in the highest elevations of the Sierra Nevada.

If my calculations are close, that's about 31 trillion gallons of water across #CAwx since Christmas. That's about 25% of the volume of Lake Erie!

There are many ways to analyze what's happened across the West over the past 3 weeks. At the end of this string of AR events, it all comes down to the extreme rainfall and snowfall totals, and the resulting impacts, especially across #CAwx. Nice maps from @NWSWPC!

The 24-hour period from 4 AM PST January 9, 2023 to 4 AM PST January 10, 2023 ranks as the 3rd wettest such one-day period since 2005 in the state of California by grid total precipitation. It was the highest in the 18-year dataset by total area of 10" in 24-hour precipitation.

A 10-panel display that maps the wettest 10 days since 2005 over the state of California, with recent 4 AM Monday, Jan 9 to 4 AM Tuesday, Jan 10 period ranking as 3rd wettest. The wettest was January 4-5, 2008, and second wettest was January 8-9, 2017.

As another Atmospheric River impacts the West, here's a look at the total precipitation from 12/24 - 1/10 across California. The excessive precipitation has resulted in many floods and even some mudslides, so be sure to protect yourself from the dangers presented by flooding.

This image shows the 17-day rainfall/liquid equivalent spanning from 12/24 - 1/10. Many areas of California have received copious amounts of rain, especially along the coast as well as higher terrain.

In the coming week across the eastern 2/3rds of the CONUS, daily high temperature anomalies will rebound from about 20-30F below normal to 20-30F above normal by next Friday! Also by next Friday, not a below normal daily minimum temperature will be found anywhere in the CONUS.

Just a handful of daily record lows forecast to break older records by a degree or two for the morning of Christmas Eve, 2022.

Just noticed the lower probability values in an unlikely place near James Bay. I bet that's where a possible punch of residual warm sector air will spread to by early morning with the #BombCyclone.

The probability of below freezing temperatures by Saturday morning is high everywhere but the western U.S.
