Friend’s Bering Sea Rule Forecast

Back on February 1st, I had a good friend of mine request a forecast for the period of February 19th and 20th in St. Louis.

At the time, I was working a ton of overtime and couldn’t get back to her right away.  However, on February 3rd I responded.

Here are the BSR depictions on February 2nd for the 19th and 20th.

This is the 00z 20FEB17 500mb OBS map…

Note the troughs over the NW and NE with a ridge between.

Note the Southerly to Southeasterly flow at 500mb.

The high temperature for St. Louis on February 19th was 72°.

While this is the forecast for February 20th.
