Here’s to a cold March through May! I’d love to see some 40s and 50s in May like we did in 2014.

Forecast low tonight: 37
Current Temperature: 36

Yes, I realize it may rise to 37 by midnight and technically verify, but it sure is chilly out there tonight!!

Currently watching Live PD on A&E right now and they are showing a live major 5+ car crash on an interstate overpass in Williamson County, TX which is one county north of Travis, Co (where Austin is).
Think I heard seven ambulances are on scene and they had to shut the interstate down on both sides because there were reports of pedestrians going over the bridges down 40ft all because of icy conditions there.

Hope the reports are wrong. Sad either way... ice is dangerous.

-------
Edit to add - officers on scene said everyone had been accounted for in the wrecks so they don't believe anyone had fallen off overpass. Don't think they ever said which interstate it was. But according to Google maps, it looks like either Interstate 14 near Killeen or Hwy 195 in Florence.

Unfortunately there were more accidents this morning in Williamson County on some major roadways as a result of icy patches.

Expect a warm evening into tomorrow with a chance of fog in the morning before another cold front moves through overnight Monday. A few scattered showers could be possible but temperatures will return closer to normal for the middle part of the week. Towards the end of the week return flow is expected and the jury is still out on how strong of a front we get on Friday. Looks like it could be one of those periods where we continually battle between cold and warm around here.

I am looking forward to seeing some sunshine this week. I does appear that after today we dry out into next weekend. There are 'hints' of another strong front early next week that may usher in a chilly unsettled pattern mid next week.

Praying for a bit more drying. Maybe we can get the rest of the yard mowed then. Tried yesterday, and could only mow about half due to the water. We planted the mower twice. The second time required us to push/pull it out of the holes it dug spinning the wheels. :shock:

334 AM CST Mon Feb 11 2019

.DISCUSSION...
Weak shortwave energy is moving across the region producing
iso/sct packets of -ra and even a lone tstm across far north
Houston Co. Elsewhere, fog is the primary issue this morning &
will monitor trends in case the dense fog advsy might need to be
expanded a bit further inland in the next couple hours.

The warm front is still situated from roughly Palacios to
Crockett early this morning. It should make some northward
progress today but slow enough whereas there will be some 5-10
degree differences in highs today across parts of the area.
Combination of weak impulses aloft and waa will continue to
produce sct shra throughout the day. Sea fog will eventually
retreat from the bays, but likely move right back in during the
late afternoon and evening hours.

Upper trough will swing thru the Plains today and swing a surface
pre-frontal trough thru later this evening followed by the front
itself late tonight. Well probably see a thin bkn band of shra and
embedded tsra develop along the prefrontal trough (and possibly
another along the front if there`s enough moisture leftover to
work with). Overall instability isn`t impressive and wouldn`t
expect much of a threat of svr tstms. May see a stronger cell or
two in the ne parts, from say Conroe-Crockett, which are a bit
closer to the rrq of the upper jet exiting ne Tx.

Tue & Wed look to be fairly nice with some periods of sunshine in
between plumes of Pacific cirrus streaming overhead. Surface high
pressure moves east on Wed. The next front should push through on
Friday. This frontal passage should be mostly dry as it looks to
be moisture starved and capped. The weekend should be mainly dry
as well...just a gradual transition period until the next system
arrives Monday-ish. 47

&&

.MARINE...
Will be keeping the Marine Dense Fog Advisory in place over the bays
and nearshore waters until just after mid morning, but could be ext-
ended until noon (per some of the short-range models). Otherwise not
too many changes with the overall forecast of a mostly light onshore
flow today/tonight along with return of sea fog late this afternoon/
early this evening. The cold front is still on track to move off the
coast early Tue morning with scattered showers and isolated thunder-
storms along/ahead of it. Brief SCEC/SCA flags will be possible late
Tue morning through the afternoon. High pressure will be building in
to the region quickly Tue night with winds decreasing. East winds by
Weds are then progged to shift to the SE Weds night as the next cold
front/storm system begins to move down off the Northern Plains. This
next front is forecast to move into the Gulf waters late Fri or so.
41

&&

.AVIATION...
Another messy start to the day as bands of weak showers contend with
the patchy dense fog already in place. These LIFR CIGS/VIS should be
improving by mid morning (expect along the coast) as the slightly el-
evated winds (20-30kts) just above the surface start to mix down. We
should continue to see these bands of showers move across throughout
the day given the persistent SW fetch aloft with MVFR CIGS remaining
in place. This next cold front is progged to move across the CWA at/
just after midnight tonight, with showers and isolated thunderstorms
likely accompanying it. However, ahead of the front, patchy fog will
be possible as VIS/CIGS fall once again. Conditions should be impro-
ving from the north to south by mid Tues morning. 41

Extended the Dense Fog Advisory until Noon for some of our far west
and northwest counties and along the barrier islands where some
visibilities remain at or below 1/4 mile. Boundary remains in/around
the inland advisory area where temperatures are still in the mid 50s.
Elsewhere, seeing 10 AM temperatures ranging from the low to mid 60s
north to around 70 in the Houston area. Rain chances will remain in
the forecast for the rest of the morning and on through the afternoon
hours.

Cold front is still on schedule to move through the area tonight,
and it will bring an end to our area`s rain fog. 42

.DISCUSSION...
There will continue to be rain chances in the forecast for the rest
of the day and overnight ahead of a cold front moves across the area
before sunrise. Cannot rule out more fog development (especially near
the coast/Bays/Gulf waters, some of which could become dense) before
the front moves on through. A couple of cool nights and mild days can
be expected behind the front as high pressure builds into the area.
As the high moves off to the east on Wednesday, look for an increase
in moisture levels and humidities to begin once again as winds come
back around to the southeast and south. Temperatures warm up once
again on Thursday as the onshore winds strengthen in response to
pressure falls in the TX/OK panhandle area, and currently anticipate
little to no rain development in advance/associated with the next
cold front scheduled to move through Southeast Texas on Friday.
Temperatures cool back down over the weekend as high pressure ridges
into the area from the north and northwest. Coastal trough development
looks possible at the end of the weekend and on into early next week
which would help to bring increasing clouds and rain chances as
temperatures remain on the cool/cold side. 42
&&

.MARINE...

Onshore flow will prevail this afternoon and tonight. Sea fog is
expected to re-develop this evening through early morning Tuesday
particularly across the bays and nearshore Gulf waters. Fog will
decrease visibilites to below 1 nautical mile, thus, the marine
dense fog advisory will likely be extended through early Tuesday
morning for the nearshore waters as well as expanded to include the
bays. A cold front will push into the coastline by early Tuesday
morning with scattered showers and isolated thunderstorms
along/ahead of it. Fog is expected to dissipate after the cold front
moves across. Moderate to strong winds and elevated seas expected in
the wake of the frontal passage, therefore, SCEC and SCA flags will
likely be in effect for the Gulf waters Tuesday morning through
Tuesday afternoon/evening. Onshore flow is forecast to return
Wednesday afternoon/evening. Model guidance shows another cold front
moving into the coastal waters Friday and could result in another
surge of winds along with elevated seas. 24

Finally the sun will return today! Light rain and showers will move off the coast this morning with clearing skies. Lots of sun through the rest of week and high temps in the 60s today and Wednesday that will rise into the 70s by then end of week and into the weekend.
