Well Forecast Month of March
Overall Very Mild & Nearly Snowless Month
Here is the 500mb forecast composite for the month of March.
Versus what has actually transpired.
Overall a very solid 500mb forecast with a bit more blocking than expected over Greenland and Alaska than expected.
The impact of the higher heights in the vicinity of Alaska (more negative EPO) was to focus the warmest anomalies slightly further to the east than suggested in the forecast composite.
Be that as it may, the higher end of forecast departure range of between 2-4F above average over the forecast area verified.
While monthly precipitation was expected to be somewhat above average across the region:
It verified well above average and ever more anomalous than anticipated likely at least in part due to the positive monthly PNA.
While this was significantly more excessive than the forecast composite implied, it was congruent with the primary analog of March 2010.
