Typical March Weather: Warmer, Then Cooler

04 March 2019   Dr. Curtis James
It’ s March, and that means weather ups and downs!

Weather Discussion:

Warmer-than-normal conditions are expected today and tomorrow, but Wednesday to Saturday, ridging will give way to troughing in the upper atmosphere as two back-to-back troughs move across northern Arizona and the Great Basin. The first trough will move through on Wednesday to Thursday morning and the second will be Friday to Saturday morning. Both of the troughs will be weakening with time as they come onshore from the west-southwest off the Subtropical Pacific, but it appears the second one will be stronger. We will have windy conditions with each one along with a chance of rain showers with each one, for perhaps about 0.10” of precipitation with the first one and 0.10” – 0.25” with the second. There is a possibility that the snow levels will drop down low enough early Saturday morning for perhaps the rain showers to change over to wet snow, but the accumulation (if any) will be minimal.

Next Monday to Wednesday morning, a third stronger storm is possible, with the potential for significant rain or snow over northern Arizona, just in time for ERAU’s Spring Break. J More details in next weeks’ forecast.
