Evening briefing from Jeff:

Highly active pattern remains in place.

Another complex of thunderstorms moved across the region this afternoon with more heavy rainfall especially west of I-45. Air mass has stabilized behind this complex as it pushes eastward into Louisiana. High resolution guidance did not handle the event well at all today…and don’t have much confidence going forward in any of the model guidance as the activity continues to be generated and controlled by the meso scale…small disturbances and ill defined boundaries.

Sure there are plenty of boundaries left behind after the activity this afternoon…most defined is right along the coast where a few showers keep trying to develop. Deeper moisture defined by “haze/smoke” on visible images is returning NW across S TX into the coastal bend and will overspread SE TX form the SSW tonight as the nocturnal low level jet increasing.

Main forecast challenge over the next several days will be timing thunderstorms and if any heavy to excessive rainfall will occur on already saturated grounds. Have very little confidence on timing of when and where storms will fire. Think the air mass is fairly worked over tonight…so not expecting anything coming out of SW TX where complexes have formed the last few days. Meso models have been hinting at storms developing tomorrow to our NE along a weak frontal zone and moving SSW into the area during the afternoon hours…this seems as much possible as any number of other solutions including storms forming over the area with heating on Monday. Storm motions looks fairly slow on Monday afternoon and evening so excessive rainfall will once again be the main threat. Unfortunately, areas that have been hit the hardest this past week (north of I-10) look to stand the best chance for heavy rainfall on Monday.

Hard to time disturbances will eject out of the SW flow aloft this week and likely develop storm complexes to our west. Upper level high pressure will attempt to gain some ground over the region and force the track of these disturbances and resulting storm complexes north and SE TX…at least that is the thought at the moment. Models have been forecasting upper level ridging to develop at the end of last week and that did not verify well.

Whole large scale pattern undergoes yet another upper level storm dropping into the SW US by the end of next week and if we do in fact get a break in the rain mid week…it looks to come to an end for the end fo the week into the Memorial Day weekend with storm chances on the increase again.

Rainfall Numbers:
If you thought it has been really wet…you are right. This is the most spring rainfall the region and state has seen in several years and it has gone a long way in helping to reduce the impacts of the long term drought that has held across much of the state since 2008.

Rainfall has been widespread and heavy in the month of May. So far this month the following sites have recorded the following rainfall through May 16th:

BUSH IAH: 3.16 (+.52
College Station: 4.48 (+2.29)
Hobby: 5.98 (+3.71)
Conroe: 7.43 (+4.93)
Sugar Land: 5.33 (+2.86)
Corpus Christi: 8.12 (+6.62)
Victoria: 3.60 (+.60)
Austin: 4.96 (+3.59)

Rainfall for the first 15 days of May is running 90% to nearly 600% of normal. The corridor from near College Station to Lake Livingston has recorded rainfall for the first two weeks of May of 300% to 500% above normal. A small area over Houston County has recorded rainfall of 600% above normal over the last two weeks. Rainfall amounts across much of south TX have averaged 200%-400% above normal.

This has resulted in the river flooding across the region and the filling of lakes that have been struggling to maintain conservation pools since the end of 2008. In fact many lakes in east Texas have been and portions of north Texas which began 2015 with below to well below normal pool levels have been in flood operations over the last two weeks.

Well above average rainfall in March and April saturated the grounds over much of Texas and the recent heavy rainfall has produce significant run-off into area rivers and lakes.

Rainfall Departures since Jan 1, 2015:
Huntsville: +13.88
League City: +13.31
Hobby: +10.46
Angleton: +10.39
College Station: +8.36
Conroe: +4.11
Tomball: +4.77
Sugar Land: +8.71
BUSH IAH: +3.61
Corpus Christi: +15.42
Victoria:+9.64

This has been the first year since 2012 in which rainfall for the first 1/3rd of the start of the year has been above average.

Water Supply and Lake Reponses:
The current state wide storage is 77.7% up from 65% one year ago and 3 months ago. This is the highest state wide storage since 2012. As good as it has been, the stats below show just how extreme the hydrologic drought has been and how much more rainfall is needed to bring some lakes to normal.

Lake: below normal (% of normal pool)
Buchanan: -29.05 ft (39%)
Conroe: +.68 (100%)
EV Spence: -70.58 (2.9%)
Georgetown: -10.50 (67%)
Sam Rayburn: +3.94 (100%)
Somerville: +8.80 (100%)
Livingston: +1.51 (100%)
Texanna: 0.00 (100%)
Travis: -49.26 (39%)
Canyon: -7.81 (84%)

Lake Travis reached a low of -58.95 (31%) around the middle of November 2014 and has since rose 9.70 ft since last November. Even with the rainfall…the amount of inflow into the Highland Lakes on the middle Colorado basin continues to be staggeringly low. Since Jan 1, 2015 to April 30th the inflow has been 70,974 acre-feet (339,651 is average) which is why Lake Travis remains so low. The April 2015 inflows were only 22% of normal. The hydrologic drought in this portion of the state has been the worst since the 1930’s and recent heavy rains have largely missed this area resulting in little drought recovery.

Mon May 18, 2015 5:44 am

Another day with heavy rainfall potential across SE TX. The radar this morning already shows heavy rains training across S Central TX and NW portions of SE TX. Street flooding will become an issue should these storms develop across Houston metro area later today.

Update from Jeff:

Dangerous flash flood event underway over SE TX.

Since 400am upwards of 5-7 inches of rain has fallen on top of already extremely saturated grounds from Columbus to southern Grimes County. Widespread flash flooding is rapidly developing over the counties of : Grimes, Washington, Waller, Austin, and northern Colorado.

This is a life threatening flash flood situation. Numerous small creeks and rural roadways are flooding. Avoid all low water crossings and do not drive into high water. Significant flooding is likely in the Flash Flood Warning areas.
