.DISCUSSION...
HIGH PRESSURE WILL STRENGTHEN OVER THE AREA THROUGH FRIDAY. SKIES
WILL BE MOSTLY CLEAR, DAY AND NIGHT, MEANING TEMPERATURES WILL COOL
OFF RAPIDLY AFTER DARK AND A STEEP SURFACE-BASED INVERSION WILL FORM.
DESPITE SUNNY CONDITIONS, THE INVERSION WILL TAKE MOST OF THE MORNING
TO BURN OFF AND ALLOW BETTER VERTICAL MIXING. TEMPERATURES WILL RISE
A FEW DEGREES ABOVE NORMAL DURING THE DAY, BUT THE ATMOSPHERE WILL
REMAIN FAIRLY STABLE BENEATH THE HIGH PRESSURE. SURFACE WINDS SHOULD
BE TERRAIN DOMINATED.
