PREV DISCUSSION... /issued 550 PM CST Mon Jan 22 2018/

DISCUSSION...
For 00z TAF issuance.

AVIATION...
Much less to talk about this evening compared to 24 hours ago. Sfc
observations show fair skies with good visibilities while satellite
imagery shows just lingering cirrus overhead. Forecast time-height
sections/soundings remain rather dry through the period except for
the persistent upper-level moisture, thus VFR conditions will
continue to prevail. Elevated nwrly winds should diminish
shortly, but somewhat elevated nrly winds should return by
tomorrow afternoon.

PREV DISCUSSION... /issued 222 PM CST Mon Jan 22 2018/

DISCUSSION...
Wx map shows cool front just clearing the coastal waters, and
quite a sight as a thin roll cloud on the GOES-East 0.5km visible
imagery. Behind the front, much drier air filtering across the
region with dewpoints in the 30s with a few upper 20s noted. With
temperatures in the mid to upper 60s, RH values ranging from
25-35%, increasing the fire danger a bit this afternoon with the
rapid drying out of the dead grass and vegetation.

Clearing skies expected to continue, with lows in the upper 30s
to lower 40s areawide by Tuesday morning. With this and another
high pressure cell to move over the region for Wednesday, near
normal temperatures expected through Thursday with no precipitation
expected.

Next rain event appears to be taking shape with multiple upper level
disturbances to affect the region for next Friday night into
Saturday time frame, followed by another cold front for late
Saturday or Sunday.

DML

MARINE...
Moderate offshore flow in the wake of the front will continue
through Wednesday night. High pressure will shift east of the
region, with moderate east to southeast winds developing by
Thursday and Friday.
