.DISCUSSION...
Issued at 234 PM EDT Mon Oct 19 2026
Fairly quiet weather pattern this week and currently high
pressure ridging building northward which will allow an upward trend
in dew points and some increase in upper level clouds which
will help to keep lows overnight tonight a bit warmer than the
last couple of nights. However, our southeastern parts of the
area the moistening will lag slightly which will allow slightly
cooler low temperatures in that area, along with the mostly
clear skies and light winds which will help in radiational
cooling. This could yield some patches of frost in those
locations. Would recommend that if in those locales that if you
have some temperature sensitive plants or animals, take proper
precautions to protect them from the cold overnight.
Otherwise, with the high pressure in place and becoming stronger
later this week with a high amplitude ridge building over the
central CONUS. This will allow for dry weather and help to keep
our temperatures warmer. High and low temperatures will run
slightly above normal with values in the upper 60s to low 70s
and lows in the 40s through the week.

Issued at 744 PM EDT Mon Oct 19 2026
VFR conditions are expected at the terminals this period. Light
and variable winds strengthen out of the E-SE Tuesday. It's
possible we see some BR between 10-13z at KFWA, but most of the
guidance has around 6SM so didn't include in the TAF for this
issuance.
