2/27 – Trey’s “Rainy Outlook” Tuesday Night Forecast

A largely zonal flow pattern will develop over the area on Friday
and remain in place through next Monday. Embedded within this zonal
flow regime, a series of fast moving shortwave troughs will sweep
through the area. The first of these shortwave features will be
moving through the area on Friday.  Ample deep layer forcing will
tap into a moderately unstable and extremely moist airmass to
produce widespread rain with some embedded elevated thunderstorm
activity.

Rainfall totals on Friday of up to 3 inches locally
cannot be ruled out.  By Friday night, the strongest forcing will
shift to the east along with the parent shortwave trough.  Weak
negative vorticity advection into the region will lead to some
drying aloft, and PWATS will fall to around an inch.  The low levels
will remain very moist as a onshore flow persists, and this will
keep skies overcast and the threat of showers in place.
Additionally, the light onshore flow and dewpoints near 60 degrees
will support the development of advection fog Friday night into
Saturday morning.  Some of the fog could be locally dense at times.

As always: A cloudy day is no match for a sunny disposition. Be nice to each other.
