...DRY AND HOT CONDITIONS WITH MOISTURE INCREASING MID TO LATE WEEK...
.BROADCAST DISCUSSION...High pressure overhead today will result in hot
and dry conditions with low humidities, but winds will remain
relatively weak. This high shifts further east by Wednesday with
moisture starting to increase, but remaining mostly dry.
Thunderstorm chances increase by Thursday and Friday.
.DISCUSSION...With high pressure overhead today expect hot and dry conditions
with relatively light winds and low relative humidity. As this
high becomes more oriented over the four corners region by midweek
moisture will increase with temperatures gradually cooling toward
the end of the week. Low levels will remain dry on Wednesday, but
some high based terrain driven convection across the southern
Utah mountains will be possible with the threat of dry lightning
increasing. Conditions will become wetter by Thursday and Friday
with thunderstorm chances spreading across most of the area and
winds, outside of convection, remaining relatively weak.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
