Surface high pressure over the Mississippi River moves east over
the Southeast, with a light flow becoming easterly by Sunday
morning over the region. With a cold airmass in place over the
region, combined with efficient radiational cooling, unseasonably
cold temperatures are expected tonight. A warmup is expected for
Sunday night as moisture levels increase, especially over western
portions of the forecast area. For tonight, temperatures a bit
warmer than last night are expected as a slightly more moist
airmass (precipitable h20 values rising from 0.3" to 0.5") moves
over the forecast area today, ranging from the mid to upper 30s
along and north of a Waynesboro to Crestview line around 40 to
near 50 south of the line to the coast. Consensus was to bump the
operational NBM down a bit, so these temps reflect that downward
nudge. Conditions are again right for frost formation tonight
along and north of Highway 84, with a Frost Advisory issued. With
southerly flow becoming more organized Sunday into Sunday night
and precipitable h20 values rising into the 0.7" to 0.85" range by
sunrise Monday, low temperatures above seasonal norms return. Low
temperatures are expected to range from the upper 40s northeast
of a Butler to Luverne line to the upper 50s to around 60 south of
I-10 to the coast. High temperatures Sunday are expected to rise
to well above seasonal norms under sunny skies. Upper 60s over
northern most portions of the forecast area to low 70s south of
Highway 84.
A light flow is expected along the coast, creating a low risk of rip
current on area beaches into Monday.
