I've been delinquent on posting about the recent monsoon rains, have now provided measurable precipitation to nearly all locations in the state. Gauge observations of precipitation over the 72-hour period ending at about 8 AM this morning show nearly everyone has gotten something, with a few stations reporting over 1.5 inches.
In some areas, this has led to flash flooding, especially in southern Utah where such flooding is common during the North American Monsoon. It is a strange combination of beneficial and hazardous weather since precipitation is sorely needed to help vegetation and lessen drought impacts, but can damage property or put lives at risk. Concerning the drought, the latest Drought Monitor shows portions of southern and eastern Utah have gone from exceptional to extreme drought. Statewide, 70% of the state was in exceptional drought last week. Currently that's down to 52%. Progress!
For northern Utah, the pattern continues to look active through the weekend. Be alert and prepared for thunderstorms and flash flooding. Although there is a tendency for such storms to be most frequent in the afternoon and evening, the storms that rumbled through the Salt Lake Valley last night show that in this pattern they are possible anytime of day. These are situations where I take a close look at the weather before venturing out, error on the side of caution if I see things deteriorating, and avoid forays into areas where quick retreat isn't possible. This isn't a situation where you want to be committed in lightning exposed or flash-flood prone areas.
