Friday. Lows will be a bit milder, in the 60s with highs in the 80s
on Friday.

Warmer conditions can be expected for the weekend as an upper level
ridge builds in with highs in the mid 80s to low 90s. Will see
chances of showers and thunderstorms through the weekend as frontal
boundary begins to move south through region. Models have
differences on timing of this boundary, so went with a blend for
now. Front to move south of forecast area Sunday night and stall out
just south of region for the first part of the work week. So chances
of storms to linger across portions of the area through Tuesday
night, before drying things out for midweek. Cooler weather is
expected behind this system and will see temperatures drop into the
upper 70s to low 80s by Tuesday and Wednesday.
