Low, dark grey stratus clouds looked to cover the whole sky, at my house in northwest Houston, TX, during the early morning. Low, dark grey stratus clouds continued to cover the whole sky, where I work in the Heights area, through the mid and late morning, afternoon, and early evening. Low dark grey stratus clouds, still covered the whole sky, at my house and neighborhood in northwest Houston, TX, during the late evening and night. It felt a little cool, during the morning, afternoon, evening, and night. The wind speeds were calm with some occasional 20 to maybe 30 mph wind gusts, where I was during the morning, afternoon, evening, and night. Heavy training rain occurred outside of my house in northwest Houston, TX, during the early morning before sunrise and continued to fall off and on where I work in the Heights area, during the mid and late morning, afternoon, and early evening. A band of really heavy rain was falling on my way to my home in northwest Houston, TX from where I work in the Heights area, during the evening. On and off light to moderate rain fell at my house in northwest Houston, TX, during the night. I thought I heard some possible distant rumbles of thunder, although I did not see any lightning, where I was during the day.
Thoughts: Well it looks like Houston definitely got a big rain event from Beta. I had the worst drive in and from work in my entire life. Especially during the evening. I drove through an hour of dark pounding rain trying desperately hard to keep my car from losing control or hydroplaning on the freeway. It was awful!!!! I am so glad for tropical storm Beta to be leaving the Houston, TX area tomorrow morning. Today is also our first day of fall.
There were multiple flash flood warnings issued by NOAA for the Houston, TX area, during the morning, afternoon, evening, and night.
Area Forecast Discussion
Issued by NWS Houston/Galveston, TX
000 FXUS64 KHGX 222356 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 656 PM CDT Tue Sep 22 2020 .AVIATION [00Z TAF Issuance]... IFR and MVFR conditions prevail. TD Beta tracks along the coastline bringing low ceilings and bands of rain that restrict visibility to IFR conditions. Tomorrow afternoon is looking like the time conditions will begin to improve across the TAF sites. Around 18- 20z, most ceilings will get to 015 and steadily improve thereafter. 35 && .PREV DISCUSSION /Issued 459 PM CDT Tue Sep 22 2020/... .SHORT TERM [Tonight through Wednesday Night]... Tropical Depression Beta, currently over southwestern portions of the CWA, has produced some very healthy rounds of heavy rain over portions of SE TX overnight/early this morning. There have been a lot of reports of flooded roadways, overtopping of bayous/creeks, and water rescues through early this afternoon. We did have a bit of a break this afternoon, but there is concern that this heating (albeit short) will help to fuel another round of heavy rains for this late afternoon through tonight. Near-term models (especially HRRR/NAM) have verified rather well of late, and if going forward with this line of thinking, we could see another band of rains de- velop close to where the earlier one set up this morning. Rainfall totals so far today have averaged from 5 to 10 inches with isolated amounts up to 15 inches. Unfortunately, we are still going with these same numbers for this evening. And so depending on where these bands set up...we could see an *additional* 5 to 10 inches of rain with isolated amounts up to 15 inches possible tonight. Bayous and drainage systems are expected to be quickly overwhelmed if this forecast verifies. Please exercise extreme caution if traveling out on the roadways tonight and tomorrow morning. As Beta moves further east tomorrow, rain chances will be slowly decreasing from the west to east. .LONG TERM [Thursday through Monday Night]... Let`s talk about good news and better weather conditions. A positively tilted trough will develop over west/central TX by midweek, while a ridge/high pressure holds strong over central Gulf of Mexico. This flow pattern will push Tropical Depression Beta northeast into Louisiana and the Tennessee Valley Wednesday night into Friday. A relatively dry-airmass will dominate the region with PWATs ranging from 1.0 to 1.3 inches Thursday through Saturday; therefore, little if any precipitation is expected through this period. The exception could be over the waters where some forecast soundings suggest morning spotty showers. Highs will generally be in the 80s and overnight lows will range from the mid 60s to mid 70s. Near to slightly above average temperatures return on Saturday as southerly surface flow brings warmer and more humid air. Upper-level flow will be dominated by a ridge over the western CONUS and a broad trough over the Great Lakes, keeping the region under a north to northeast flow aloft this weekend into early next week. At the surface, a cool front will cross Texas on Saturday, approaching our region by early Sunday. Unfortunately for us, not much is expected with the arrival of this front, other than a wind shift through Monday. Latest GFS solutions suggest some rain showers across our far southwestern counties; while the ECMWF and Canadian keep the period dry. Have leaned towards the latter solution and kept the period dry. The main feature next week will be slightly warmer temperatures returning into the region. Daytime highs are expected to reach the upper 80s to lower 90s. .MARINE... Tropical Depression Beta has moved inland and is losing strength. Effect on the coastal waters are subsiding. A Small Craft Advisory is in effect through Wednesday morning and at this time is not looking like it will need to be extended. Through the night the winds wind in the coastal water are going to be northwesterly around 15Kts and seas at 3-4ft just off the coast with 5-6ft in the outer waters. By Thursday the seas will subside to around 2ft just off the coast with 3-4ft in the outer waters. Winds will be northerly around 10kts. Thursday morning will be the final push of chances of rain in the coastal waters. Through the weekend, fair winds and following seas with light onshore flow developing over the weekend. .HYDROLOGY... Rainfall rates have tapered off significantly since early morning and this has given many of the river and bayous a chance to recover some capacity. The hardest hit corridor remains from around Bellaire to South Acres in south Houston to Brookside Village/Pearland/Friendswood where the swath of the heaviest rainfall 9-14" fell. Currently the largest impacts are along the Clear Creek basin. From around Morningside Place north of Tom Bass regional park downstream through the I- 45/Clear Creek area. Moderate flooding levels has gotten into homes there and will likely continue at or near these same levels through 11 pm to 2 am before starting to significantly recede...first on the upstream sites this evening then into hardest hit areas below Telephone Road tonight. Needless to say that the area doesn`t need any more rainfall but the slow moving circulation with Beta is likely keep the threat of locally heavy rainfall with 2+"/hour rates in the picture through early Wednesday. With some of the eastward shift of the heavier rainfall in the short term guidance these higher rainfall rates may be focused east of these hardest hit areas early today which would be good news for these area. But it may also be clipping the eastern edges of these basin. The threat for impacts tonight is likely to shift generally along and east and northeastward of the I-45 corridor. && .PRELIMINARY POINT TEMPS/POPS...
