𝐒𝐞𝐯𝐞𝐫𝐞 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐚𝐧𝐝 𝐅𝐥𝐚𝐬𝐡 𝐅𝐥𝐨𝐨𝐝 𝐓𝐡𝐫𝐞𝐚𝐭 𝐟𝐨𝐫 𝐌𝐨𝐧𝐝𝐚𝐲 (𝟑/𝟐𝟏) - 𝐓𝐮𝐞𝐬𝐝𝐚𝐲 (𝟑/𝟐𝟐)

A strong storm system will approach the Katy area tomorrow, with an associated cold front passing through the area overnight and into the early hours of Tuesday.

By tomorrow (Monday) afternoon, the environment will become favorable for the development of severe thunderstorms. Storms may become strong to severe, with large hail, tornadoes, and damaging wind gusts all possible in any strong storms that develop.

The main threat will transition to flooding as the cold front moves through the area overnight, with heavy rainfall potentially leading to street flooding. There remains some uncertainty regarding the exact location of the highest rainfall totals as well as the highest rainfall amounts. However, widespread rainfall totals of 2-4" with locally higher amounts will not be uncommon.

✅Review your severe weather safety plan today!
✅Be sure you have MULTIPLE ways to receive warnings.
✅Stay tuned to the latest forecasts.

Scattered showers and thunderstorms will develop during the late afternoon and evening tomorrow ahead of an approaching cold front that will move through the Katy area after midnight.

There is a potential for a few storms that develop to become strong to severe, with the main threat window for strong storms from approximately 6 PM to 2 AM. Strong storms may produce large hail, isolated tornadoes, and strong wind gusts.

03/11/2022

A strong cold front is currently on its way to the Katy area with decreasing temperatures and moderate to strong northerly winds in its wake.

Expect the cold front to push through the Katy area around 9am. In addition to the falling temperatures, isolated to scattered rain showers will continue to develop ahead of the frontal boundary with widespread showers and isolated thunderstorms expected this afternoon.

Moderate to strong northerly winds will follow in the wake of this morning's cold front with sustained winds of 20-25 mph and gusts up to 35 mph. A Wind Advisory is in effect from 9am this morning through 12pm on Saturday as a result.

Cold temperatures combined with strong northerly winds will equate to frigid wind chill values. Temperatures on Friday night/Saturday morning will drop into the upper 20s/low 30s for most of the area, but with the wind factored in, it'll feel like the upper teens/low 20s.

Don’t underestimate the power of water. It only takes 6 inches of fast-moving water to knock over and carry away an adult, and 12 inches to carry away a small car.

NEVER drive or walk into floodwaters. It is impossible to know how deep the water is just by looking at it.

NEVER drive around barricades into floodwaters! More than 50% of all flood fatalities are vehicle related.

Are you prepared for flooding before it happens?

During a flood, water levels and the rate at which water is flowing can quickly change. You are safest staying indoors, or seeking higher ground if shelter isn’t available. If you’re stuck outside when a flash flood occurs, do not attempt to cross flood waters by vehicle or on foot.

Most flood fatalities occur in vehicles, and it only takes 12 inches of water to sweep a car away. Small decisions can make the difference between life and death. During a flood, small decisions like turning around and not driving through a flooded roadway, not driving around barricades, and delaying travel until conditions improve can make a big impact on whether you keep your car—or even your life. Turn Around, Don’t Drown.

You know to take shelter immediately if your area receives a Tornado Warning. But what makes a good shelter? Take the time now to figure out your options.

If you’re relaxing at home...when all of a sudden, a Tornado Warning comes through on your phone or NOAA Weather Radio. Where will you go to stay safe?

If you are outside during a tornado warning, the best option is to drive to a designated shelter, basement, or safe room. Seeking refuge in a vehicle or under an overpass is NOT safe.

Do you know the difference between a Severe Thunderstorm Warning and a Severe Thunderstorm Watch?

A Severe Thunderstorm WATCH means Be Prepared. Stay informed and be ready to act, because severe thunderstorms are possible.

A Severe Thunderstorm WARNING means Take Action! Take shelter in a strong building, because severe weather is occurring or will occur shortly.

There is the possibility of minor icing on elevated surfaces north and west of Katy. At this time it does not appear to be an issue for our area.

Current Katy Advisories and Warnings:
Winter Weather Advisory from 2:00 pm Thu. 2/3/2022 to 12:00 am Fri. 2/4/2022
Hard Freeze Warning from 6:00 pm Thu. 2/3/2022 to 9:00 am Fri. 2/4/2022
Wind Chill Advisory from 6:00 pm CST Thu. 2/3/2022 to 9:00 am Fri. 2/4/2022

The freezing line will continue to move southeast and into Katy by late afternoon and early evening. Rain will continue and then change to freezing rain behind the freezing line. Winds of 20-30mph today coupled with cold temperatures will result in wind chills in the teens and 20’s for much of the day. The rain will gradually end this evening, but there is the possibility that some light freezing/sleet could fall during the overnight hours.

Accumulations of .01 to .10 of an inch of ice remain possible in Katy with most likely accumulations on elevated surfaces. This includes, bridges, overpasses, flyovers, trees, power lines, roofs, and vehicles. Accumulation on surface streets, sidewalks and parking lots is not expected given the warm ground temperatures.

If traveling this evening into Friday morning please use extreme caution. Bridges may appear wet, but there could be patches of ice on it. It is very difficult to tell the difference. Slow down below posted speed limits when approaching any bridges.
