.DISCUSSION...
Another dry day today. Skies will be mostly sunny this morning,
though some partly cloudy skies arrive by early afternoon and
clouds increase late afternoon into tonight. Mixing heights start
out around 2100 ft and rise to 5600 ft this afternoon. High
pressure over southern Canada will keep winds lighter, turning
southeasterly at 5-7 mph with gusts to 8-12 mph. High
temperatures rise into the upper 60s, with min RH values dropping
to around 30%, though could see RH dip into the mid to upper 20s
if mixing is deeper this afternoon than expected. Smoke dispersal
will be poor to fair to start, and improve to good by early
afternoon.
Slight chance of very light rain showers late overnight into early
Wednesday morning. Otherwise, expect rain chances to increase
starting early Wednesday afternoon and persist into at least
Thursday morning. Because of the rain, late morning and afternoon
min RH drops to the 45-50% range, though mixing heights only
reaching around 2900 ft.
