.DISCUSSION...
Overall dry conditions expected through the end of the week, with
temperatures reaching up to the 70s on Thursday, 80s on Friday,
and RH values dropping down to 10% each day. On Saturday,
isolated-scattered virga showers are possible (20-30% chance) in
the afternoon/evening. However, wetting rain is unlikely given the
dry air mass at the surface. If a stronger storm were to occur
over the burn site, expect <0.10" of rain accumulation. Lightning
and gusty erratic outflow winds will be the biggest threats.
The best chance for wetting rain will be Sunday, where widespread
showers/thunderstorms are becoming more likely across the area. As
of right now, there is a 30% chance of 24-hr rainfall accumulation
>0.25" by Sunday night (50-60% chance of accumulation >0.10").
Moisture will likely linger around on Monday, with minimum RH
values hovering around 40-50%. Afternoon showers are possible, but
wetting rain is unlikely given weak instability.
Very low chance (<20%) of afternoon showers/thunderstorms by
Tuesday and Wednesday, with temperatures climbing into the 70s
and 80s. A dry air mass is expected to move into the region, with
minimum RH down to mid 20% on Tuesday, and 15-20% on Wednesday.
