Summary: A cluster of light to really heavy showers and thunderstorms passed over most of the Houston, TX and Katy, TX area during the early morning, followed by some isolated light to maybe moderate showers through the rest of the day. There were tornado warnings and flash flood watches and warnings issued. There was a tornado reported in north Houston, TX at around highway 99 and I-45. It ripped up roofs and blew a few trees and fences down. Other than that there were just a few big puddles and blown leaves left over from the thunderstorms and showers. My parents said that they saw high wind and that our power went out for a few seconds at our house in northwest Houston, TX, from a strong thunderstorm that passed over during the early morning. I just saw some moderately heavy to really heavy rain, but no wind, or lightning and thunder, as I was driving towards west Houston, TX, where I work, during the early morning. The rain had stopped when I arrived at work in west Houston, TX during the early morning. Most of the heavy rain was located in Katy, TX and northwest Houston, TX during the early morning. I didn't see any rain after the early morning showers and thunderstorms.

Thoughts: Well a tornado went through Houston, TX today. That was unexpected. It was only a F-0, but it still caused some significant damage.

000 FXUS64 KHGX 162350 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 550 PM CST Mon Jan 16 2017 .AVIATION... Weak, shallow frontal boundary continues to sag into northern parts of se Tx. This feature will be slow moving and eventually pull up stationary from maybe roughly Edna-Houston-Cleveland late Tue afternoon. Moisture will override this boundary, and weak impulses in the upper flow will initiate periods of shra (maybe some very iso tstms) along and north of the front overnight tonight thru at least Wed. Flying conditions will be varied depending on frontal location and precip, but in general anticipate MVFR/IFR conditions to mostly prevail. Sea fog will also be a concern in the metro area southward later tonight and Tue morning as well. 47 && .PREV DISCUSSION... /ISSUED 355 PM CST Mon Jan 16 2017/ Though in a relative lull in activity this afternoon, the story for most of the week will be continued unsettled weather. Like we`ve seen today, the character of expected precipitation is not expected to be continuous rain, but there will be high chances for off and on showers and storms through Thursday, occasionally enhanced by passing weather features. The severe weather around the Houston metro this morning was likely the best opportunity for severe weather in this period, but some more is possible ahead of a cold front today, and can`t be totally ruled out along the coast tomorrow. Friday does look to be drier in the wake of a coastal low, but some chance for precipitation should return for the weekend. Finally, a cold front Sunday morning should clear things out for the first half of next week. Rest of today through Thursday... Radar shows showers still ongoing in our north, and while there have been a smattering of light echoes farther south, the limited vertical extent of cumulus outside the window implies the cap has indeed been too strong to overcome, despite the extra heating. Indeed, SPC mesoanalysis shows at least moderate instability for the region, but MLCAPE is significantly lower (and with CINH!), and it appears that is what`s winning out. Winds at College Station have switched to consistently northwest, and the dewpoint has dropped to 62, suggesting it has seen the arrival of the oncoming front. However, this appears to be a bit of a vanguard, as an APRS site in Madison County and Crockett appear to be ahead of or just entering the frontal zone at 3pm. The front should continue to advance, and provide a focus for continued showers and perhaps a storm. There does seem to be a modest amount of low level shear near the front, so don`t want to rule out some organized updrafts for the strongest cells, especially if, like this morning, we get low-topped convection. Similar to the SBCAPE/MLCAPE comparison mentioned earlier, while MLCAPE is limited at this hour, mesoanalysis shows available MUCAPE, and the front may be enough to tap into any remaining instability for the nighttime hours. That said, none of the HRRR, TTU WRF, or NCAR WRF ensemble spark more than numerous light showers until a subtle midlevel shortwave comes through Tuesday night into Wednesday morning. So, this concern may simply be for naught. After the subtle midlevel trough passes through to enhance PoPs for Tuesday night and Wednesday, we drop back down to more of a "baseline" high chance inland, while PoPs remain elevated near the coast as a coastal trough/weak surface low develops Thursday and moves up the coast. Once it moves through, some brief offshore flow wrapping around the low pressure center looks to dry things out briefly, though onshore flow should return by sunrise Friday. Friday and beyond... Though the models suggest some light rain near the coast Friday, opting for now to stay dry until perhaps Friday night or Saturday and a closer approach of the next front. As the next bowling ball upper low ejects through the area Sunday, we should see a surface low roll through Oklahoma, and bring a clearing front through Southeast Texas Sunday morning. After that, brief midlevel ridging should keep things quiet into early next week. Luchs && MARINE... Seas of 5 to 6 feet offshore this afternoon should gradually come down tonight as winds relax and cold front creeps southward over SETX. Expect the very moist airmass with dewpoints in the upper 60s to flow over the cooler shelf water which should become more favorable for the formation of sea fog if a little more dry air just above the surface isn`t present than what soundings indicate. Fog threat especially after midnight through mid morning and possibly longer as winds back to the east southeast. This pattern holds through Wednesday before a more potent short wave kicks through and could increase winds and veer them to more southerly in direction possibly lessening the fog threat. Potent system arriving Sunday/Monday and will likely bring SCA and possibly westerly Gale conditions to the coastal waters. 45 && Fire Weather... Wet across the area through Saturday for the most part so low fire concerns. Potent Pacific frontal system will swing through late weekend/early Monday and has the potential to bring dry/very dry conditions with abundant wind so may have a slight uptick in fire threat Monday. 45 && .PRELIMINARY POINT TEMPS/POPS...
