I meant last real shot for a freeze. Of course we will continue to have cold fronts, probably into May. But the trend will be up.

NWS has raised tomorrow night’s forecast low to 33.

We’ve had some freezes in March before though. We had one last year if I remember correctly and I think in 2002 we got down into the teens the first week of March.

Area Forecast Discussion
National Weather Service Houston/Galveston TX
1145 AM CST Wed Feb 26 2020

.AVIATION [18Z TAF Issuance]...
VFR. Gusty northwest winds 15-25kt G 25-35kts this afternoon
diminishing and becoming light and variable late this evening as
high pressure settles into the Hill country/Coastal Bend. BKN-OVC
3500-4500ft deck wrapping around shifting southeastward with time
through the afternoon while eroding from the edges. SKC should
follow after this departs into East Texas.

45

.PREV DISCUSSION /Issued 1001 AM CST Wed Feb 26 2020/...


.SHORT TERM [Tonight Through Friday]...
Cloud deck expanding southward with some erosion on the western
fringes. Temperatures will be nearly steady or rising only
slightly this afternoon as the sun peeks through. Wind advisory
remains in effect and don`t foresee expansing the advisory as
stronger winds should be in a belt across the western half of the
area.


45


.LONG TERM [Thursday night through Wednesday]...

The first half of this period will be uneventful as the state
still remains under a mid to upper level northwesterly flow
pattern. At the surface, high pressure will rule through the
weekend. This will translate to very dry and pleasant late week
weather conditions...clear skies with light and north/west veering
variable breezes. Subsequent late February days will warm from
the early morning upper 30s/lower 40s (Thursday) to the 50s (by
Sunday AM) as days warm from Thursday afternoon`s mid to upper 50s
to Leap Year - Saturday`s lower 70s.

March begins on a different yet very familiar note. Return flow
overnight Sunday morning will begin the moisture pump that will
take weekend sub-inch pwats to around 1.3 inches (between the 75th
and 99th percentile for early March) by Monday. Early week zonal
flow will back more southwesterly as models forecast a sharp
Plains trough that will dig well into northern Mexico. This deep
trough axis is forecast to sweep/lift across the state early
Wednesday. This scenario will strengthen Sunday through Tuesday`s
southerlies, thicken up clouds and introduce low end chance
drizzle/streamer shower chances to Monday`s forecast. Despite the
fairly aggressive nature of the mid-upper longwave trough`s
approach and passage (or lift across the Piney Woods), the
surface reflection of the associated cold front will not come
through with much fanfare Tuesday. Moderate chances for rain and
isolated thunderstorms focuses across the northern CWA Tuesday
afternoon in relation to this front`s dynamics. The larger story
may be the unseasonable warmth as this warm air advection pattern
may stick morning lows in the middle to upper 60s with afternoons
warming into the upper 70s to lower 80s (by Tuesday). A more
westerly wind on Wednesday in the wake of the lower level boundary
will `regulate` temperatures back into the morning 50s/afternoon
upper 60s to lower 70s. 31


.MARINE...
NNW winds and seas will further increase into the morning hours.
Will maintain current hazard setup with advisories in the bays thru
sunset. Gale warnings will continue in the Gulf until noon, then
being replaced with advisories into tonight. Water levels will
bottom out between -0.5ft and -1ft MLLW during the next low tide
cycle. This is just above low water advsy criteria, but should be
taken into account of regardless esp larger vessels for grounding
purposes. Winds/sea begin to slowly diminish tonight and Thursday as
surface high pressure expands into the region. As the high moves off
to the east, look for onshore winds will resume Saturday and gradually
strengthen into early next week. Caution/advisories may be required
again by late weekend. 47


.FIRE...
Elevated fire danger today. Afternoon humidity falling into the 30
to 35 percent range or lower with gusty NNW winds 15 to 25 mph with
gusts of 30 to 35 mph. 47

Tonight very well could be the last area wide freeze until next winter. Outlying areas could dip near freezing again Friday morning, but most should stay in the mid 30s.

Very spring like weather looks to take hold across much of the country as we head into March.

True. We even had snow flurries in April a few years ago. But the pattern looks like it’s shifting such that this is probably the last freeze threat for the season.

My low has been raised back up to 33.

My lips are chapped and my face feels like sandpaper today.

I'm at 43 with a dew point of 29. Areas northwest of Magnolia are already at freezing. Just checked KHOU and they show 32 for IAH. It's gonna be a close one. I'm not gonna go out and cover anything at this point. All of my sensitive plants are under a tree canopy and against a fence to the north.

Edit: Low just lowered to 32. Figures.

Looking NW off my front porch this morning. Right at 2 inches with a NW flow snow event. We have a clipper system arriving tomorrow afternoon with another 2 to 3 inches expected.

Area Forecast Discussion
National Weather Service Houston/Galveston TX
400 AM CST Thu Feb 27 2020

.SHORT TERM [Through Friday]...

With a dry northwest flow aloft and surface high pressure over
south Tx drifting eastward into the upper Tx coastal waters, look
for clear skies thru the period. Overnight lows in the 30s will
rebound to near 60 today...and around 70 Friday. 47


.LONG TERM [Friday night through Thursday]...

A northwest upper flow pattern backing more zonal through the
weekend, in tandem with regional surface high pressure centered
off to the east, will ensure a very dry and pleasant start to
the weekend. The mainly clear Leap Day (Saturday) will begin cool
with inland low to middle 40s / coastal lower to middle 50s and
will warm into the interior middle 70s / coastal upper 60s as
onshore flow returns through the day.

Early March will begin much more warm and humid as southerlies
strengthen and increase PW`s into the 1.30 inch range through
Tuesday (above the 75th percentile for early March). Partly
becoming mostly cloudy early week days with slight precipitation
chances for streamer showers on Monday. Very stout southerlies in
the 10 to 20 mph range will be what enhances a warm/moist air
advection regime as mid layer southwesterly winds downstream of
an approaching U.S. Southwest trough push 850mb temperatures back
up in the lower to middle teens (deg C). Hence, much warmer early
day conditions with minimum temperatures in the lower to middle
60s...days warming well into the middle to upper 70s.

Models still show a deep upper trough entering the state late
Tuesday and then lifting up and over northeast state early
Wednesday. The deepness of this trough is projected to produce a
split jet feature over East Texas overnight Wednesday morning.
The best upper level dynamics and lower level frontogenesis will
occur during the overnight hours Tuesday night into early
Wednesday morning. While shortwave energy riding up and over
eastern Texas Tuesday afternoon generates periods of rain and
possible isolated (elevated) thunder, the best chance for the
strongest weather/highest QPF will be focused over the northern
half of the CWA Tuesday night into Wednesday morning. The front
will sweep through early Wednesday and clear any lingering light
rain and cloud cover out to the east mid to late Wednesday morning.
Mainly clear skies under westerlies Wednesday afternoon as the
day warms from the 50s to the 70s. A reinforcing dry cold front on
Thursday will veer winds more northwesterly and strengthen them
while advecting in a much drier air mass (sub 0.20 inch pwats). As
of now, late work week humidities are progged to be very low as
dew points plunge into the lower 20s by Friday morning. The cold
air advection will not be as strong as this dry air intrusion but
still strong enough to regulate a mostly sunny Thursday afternoon`s
maximum warmth to the middle to upper 60s. 31

&&

.MARINE...
Will extend the low water advisory until 8am for the bays (mainly
the northern peripheries)...which should cover the next low tide
cycle. Look for gradual recovery thereafter. Will also maintain the
caution wording in the Gulf for a few more hours with ongoing 15-
20kt north winds. Speeds should continue diminishing thru the day.
Surface high pressure will move eastward and into the upper Tx
coastal waters today...eventually exiting to the east on Saturday.
Onshore winds will then resume. A lengthening fetch of moderate to
strong sse winds and building seas are then expected into early next
week. A combo of caution/advsy flags is possible as early as Sunday.
Dependent on conditions at the time, we`ll also be on the lookout
for possible sea fog development Mon/Tue but wind speeds appear to
be a limiting factor. The next wx system & associated cold front is
penciled in for Tue night. 47

No idea how cold it ended up here at my house. I’d say somewhere in the mid to upper 20’s. It was already down to 31 at 3am here so I’d estimate 27 or 28.

I’m ready for some rain and storms now. I saw channel 13’s forecast earlier and noticed they had 60% for next Tuesday. Maybe I’ll get something then. The Euro calls for about an inch of rain widespread across SETX, but the GFS keeps it well north and east of interstate 10.
