Winter storms brought significant rain and snow to much of Wyoming during the month, giving the state a rank of 16th wettest March on record. However, severe long-term moisture deficits remain, with April 2002-March 2003 ranking as the 12th driest such 12-month period.
According to the Wyoming State Climatologist (Jan Curtis):
Temperatures for the month of March were quite varied across Wyoming. Average temperatures ranged from >6 degrees F above normal in Sublette and Lincoln counties to <4 degrees F below normal in Sheridan county. Precipitation for the month of March also showed large variation across the state. The heaviest moisture amounts fell in portions of extreme eastern Wyoming and the northwest mountains (>200 percent of normal), the least over Carbon and Fremont counties (<25 percent of normal).
Since 1895, Wyoming had the 16th wettest March on record. Contribution from a couple of intense snowstorms helped lessen the impact of the four-year statewide drought.
