.DISCUSSION...
For Tuesday, Wednesday, and Thursday, high temperatures should be
in the mid 50s with lows in the upper teens to low 20s. Only a
few clouds each afternoon. Skies could become mostly cloudy by
late Thursday afternoon into the evening, but the forecast could
change as we get closer. No precipitation is expected. Winds look
gusty each afternoon (Tuesday through Thursday) this week with
south to southwest winds and gusts of 25-30 mph possible. Relative
humidity should drop into the low 30s on Tuesday and Wednesday
afternoons with RH even dropping in the low to mid 20s on Thursday
afternoon. Humidities should recover very nicely each night. Smoke
dispersal is expected to be good to very good on Wednesday
afternoon as well as Thursday afternoon.
Note: We are not able to do a tabular forecast after Tuesday at
this time, but can send an updated forecast later this week if
desired.
