Weather Trader | Thursday Afternoon Update

Bomb\u2019s away!

We are within the window of time to be fairly certain of a \u201cbomb cyclone\u201d developing in the lee of the Rockies, slowing intensifying until reaching the East Coast, and then explosively deepening off the coast. The storm will have enough cold air on mid-February to develop narrow snow bands that could be quite significant in North Texas and Oklahoma.

\"\"

The track of the low will determine if/where and how much snowfall is expected from Texas to New England (obviously) but there is plenty of moisture and enough cold air to produce significant accumulations, at least at night.

7-day Snowfall | ECMWF 12z HRES | weathermodels.com

Zoomed in view of the HRES snowfall. This has been moving north/south for the past 2 days of forecasts. Maximum of 12-17\u201d away from the coast with 3\u201d-5\u201d in NYC and 9\u201d-12\u201d in Boston.

\"\"

Quick look at the GraphCast-ECMWF A.I. (non-commercial/experimental) as a cursory check on the ECMWF\u2019s accuracy. A.I. seems to match up closely at Day 5, which is a good sign since the forecast skill is > 92-95% as of late.

Tuesday afternoon

Looking at Sunday across North Texas = heavy snowfall!

And the resulting snowfall through late Sunday could be significant accumulations from Lubbock to OKC.

Next 14-days Daily Temperature Anomaly

\"\"

Not seeing any major blobs of brutal Arctic air for the next 2-weeks even if below normal temperatures pop up for a few days. Running out of winter fast.

7-day Total Precipitation from WPC

\"\"

Moisture ahead of the \u201cbomb cyclone\u201d will keep the Southeast warm and wet over the next few days. California finally gets a dry spell for the next week.

15-day Snowfall ECMWF EPS Median Accumulation

\"\"

Since there\u2019s little rainfall/snowfall on the WPC map through Day 7 across the West, you can surmise that heavy snowfall will again come back to California in Week 2 and the entire Western U.S. as we go back to a familiar weather pattern: blocking ridge over Canada and troughs along the coasts.
