.DISCUSSION...
High fire danger conditions are expected today due to low RH.
While surface winds remain southerly through today, this is not
going to do much to keep RH and fuels from dropped as we head into
the afternoon. We did issue an updated RH forecast and latest
forecast minimum RH at the burn site is near 23%. RH values are
expected to drop below 25% for several hours this afternoon
largely after 12-1PM and lasting through 7-8PM.
Fog development is not expected to be a concern for Thursday
morning as cloud cover will be on the increase and winds will be
elevated. The earliest onset of any rainfall at the burnsite on
Thursday will be 12-1PM. Thunder chances will also increase after
1PM Thursday. Initial rain will be light. Any thunderstorms that
develop during the afternoon are likely to result in gusty
variable winds. Rain comes to an end Thursday night. Forecast
rainfall totals are at 0.2" or less. Minimum RH values drop to 50%
on Thursday.
