.PREV DISCUSSION... /issued 350 AM CDT Tue Mar 20 2018/

The anticipated second frontal boundary is denoted this morning on
satellite by a narrow band of low level clouds moving through
southeast Texas. Temperatures behind the front are running about
10 degrees cooler. The front will continue to progress southeast
through the morning and should clear the area by mid morning.
Winds are expected to increase to around 15 MPH with gusts to 25 area
wide by late this morning and will continue through the afternoon
before weakening during the evening as high pressure begins to
build across the region.

The remainder of the work week will be dry and very pleasant with
plenty of sunshine, afternoon highs in the mid 70s and overnight
lows in the mid 40`s to lower 50`s. Winds will turn back out of
the south on Thursday as high pressure pushes off to the east
which will allow the dry airmass to begin to moderate.

The next chance of precipitation doesn`t look to enter the picture
until late this weekend although guidance remains inconsistent as
to how much moisture will be available. Both the GFS and the ECMWF
develop a large upper low over the western US early next week,
but have much different solutions with regards to the impacts of
this feature across our area. Thus, inserted only low end pops
towards the end of the forecast period until the evolution becomes
more clear.


A cold front will push through the coastal waters this morning
allowing for the development of moderate and gusty northwest winds
that will persist through much of the day. Small craft advisories
are in effect. Winds will subside Tuesday night into Wednesday
morning as high pressure settles across the area. Southerly winds
return Thursday as the high moves off to the east with a modest
onshore flow developing to end the week.

A dry cold front will push through the area early this morning ushering
in cooler and drier air in its wake. Winds behind the front will turn
out of the northwest and increase to around 15 MPH by this afternoon. These
gusty winds combined with low RH values in the 30 to 40% range will make
outdoor burning hazardous this afternoon. Winds will weaken
