Your support has generously funded my Linux servers for product development. So far, I have been able to build RRFS, downscale WRF, and other \u201cForecast Point\u201d products that I am rolling out as soon this weekend on https://weathertrader.com. The idea is that Substack subscribers will get forecast(s) at a location(s) with considerable value-added information. I will create an example page for LAX and you\u2019ll see how it works. There\u2019s more to a forecast than what you pull up on your Phone App like Weather dot com or AccuWeather.

Weekend High Temperatures

Saturday Highs | February 3, 2024

\"\"

You can find some chilly air, or at least seasonable, over northern New England with highs in Maine in the 20s. Otherwise, 40s across the upper Midwest and Great Lakes are an astounding 15\u00b0F to 25\u00b0F above normal especially in the Dakotas. It could be -40\u00b0F rather than +40\u00b0F in early February.

Next 15-days Daily Temperature Anomaly

The block breaks down!

\"\"

After long last, it appears there is a pattern shift on the way! Instead of cold in Alaska and Greenland and warmth centered upon Canada with the blocking ridge, the opposite pattern takes hold by mid-February. Bye bye Omega Block! Maybe the Groundhog was wrong?

15-day Snowfall ECMWF EPS Median Accumulations

\"\"

Not much has changed with the 15-day median snowfall forecasts \u2014 looking past mid-February for any sort of winter storm signal east of the Rockies.

Looking at 6-inch snowfall probability and the signal is < 20% from the Great Lakes to the Northeast except for some potential lake effect accumulations. This is pretty much a snow bust for 10-14 days, or longer. However, as the block breaks down, there\u2019s a much better chance for winter storms and a more typical progressive upper-level pattern with the jet stream in the typical climatological location.

\"\"

The Western U.S. ski resorts will be enjoying massive accumulations \u2014 full tilt!

Quick look at Boston and Chicago for snowfall chances to look for signals of \u201cbig systems\u201d and a change from earlier today and yesterday: I see a handful of winter storms, which inputs into the probability maps to get 10-20% of 6-inches+.

Mild weather across the southern U.S. from the Plains into the Southeast. 60s in the early evening feels wonderful. Even some 80s in South Texas along the Rio Grande. Warmth continues for the next 7-10 days until the \u201cblock breaks down\u201d finally!
