MARCH 2001 WX REVIEW

A rather benign March with only one decent rainy period, a 6 day event featuring a now-typical upper/lower level low tandem during the first week of the month. A very modest 1.03" fell from the event, with better dynamics to our south. Perhaps most noteworthy for the entire month was a string of beautiful, warm spring-like weather between the 18th and 22nd, which produced the year's first 70 + readings on the 19th and 20th. Offshore winds developed after a dry frontal passage with the parent low kicking east to our south then anchoring over the four corners region as high pressure built inland to it's north...a classic pattern, but actually a little unusual for this time of year. Generally speaking, weather systems become quite progressive this time of year, and as such rarely hang around long enough to get a true offshore event established. However, this year has been anything but usual, and the offshore pattern has been dominant on numerous occasions all Winter. Unless MAJOR rains come in April/May (highly unlikely), the yearlong trend of above average rains to our south and below average rains to the north will be the final outcome to this year of "La Nada". Flora and Fauna seems considerably more robust than in recent years, as the cherry trees and other annuals are in full bloom with heavy foliage. As noted in earlier reports last Fall, flora seems more in sync with the calendar than in many, many years. While this may bring good yields for crops and such, there will also be a high fire danger.
