Weather Patterns Turning Spring-Like

Well it's that time of the year - the weather patterns are starting to show characteristics of spring.

Let's start with the US snow cover - it is slowly but surely eroding and heading north - see the map below.

The prolonged snow cover this year has kept much of the nation locked into below normal temperatures. In fact, I heard a weather statistic yesterday that February had no tornadoes recorded in the United States - the first time this has happened since 1947.

With the rising sun angle, longer days ahead, and no snow cover across the southern tier of states - we will start seeing a larger contrast between the air masses as you travel north to south.

This will set the stage for spring storm systems that bring snow and cold on the north side and west side with thunderstorms and warm, humid air on the south and east side.

Get ready for an active week to 10 days ahead as a series of storm systems move along the jet stream across the center of the nation. Below is a map outlining a few of the larger threats we will face in the next 10 days.
