.DISCUSSION...

KEY MESSAGES:

1)Scattered thunderstorms this afternoon and evening may produce
brief downpours and gusty and shifting winds.

2) Upper ridging is expected to set up next week leading to hot
and dry weather conditions. At this point, Thursday appears to
offer the chance for near excessive heat with highs in the mid 90s
to low 100s and overnight lows in the 60s.


WEATHER PATTERN OVERVIEW:

Scattered thunderstorms will continue this afternoon and evening
with brief heavy downpours and gusty and shifting winds. Storms
will diminish in coverage this evening and winds will become light
out of the northwest.

Upper ridging will begin to set up in the western CONUS and extend
eastward next week. Large scale subsidence will lead to drier
weather conditions across the region as temperatures trend warmer
and eventually hotter. At this time, Thursday has the potential to
be near excessively hot with high temperatures in the mid 90s to
low 100s and overnight lows in the 60s. While this period remains
several days out, heat products may need to be considered in the
coming days if trends continue and confidence increases. Given the
recent pattern of near to below normal temperatures, impacts from
the coming heat may be exacerbated.

FORECAST CONFIDENCE & DEVIATIONS:

Confidence is low on the exact timing and placement of individual
thunderstorms this evening, but high that active weather in
general looks to continue for a few more hours.

Confidence is also high that upper riding will yield dry weather
and a warming trend next week. Conditions will be monitored for
the potential for heat related products in the coming days.
