The sky started out cloudy during the early morning, then became clear to mostly clear, through the rest of the morning and early afternoon with some thick clouds appearing from time to time. Scattered stratus clouds covered the sky during the mid and late afternoon. The sky looked to be cloudy to mostly cloudy during the evening and night.

781 FXUS64 KHGX 240226 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 926 PM CDT Tue May 23 2017 .UPDATE... Main updates to the forecast tonight have been clearing counties from Severe Thunderstorm Watch 259. The surface cold front and associated thunderstorm activity continue to push off the Upper Texas coast tonight, taking the threat for severe weather with it. The KHGX radar is showing a secondary line of showers developing approximately 100 miles to the north in the vicinity of the 850 MB front. Despite a uniform wind direction at this level, there is sufficient speed convergence along this feature (30 knot winds flowing into 10 knot winds) to result in isolated to scattered showers. The atmosphere as destabilized significantly since this evening`s storms moved through and severe weather is not expected, but cannot rule out a rumble of thunder. Otherwise, remainder of forecast remains on track with dry conditions expected after midnight and clearing skies allowing overnight temperatures to fall to the mid 50s to mid 60s... much below normal for this time in May. Huffman && .PREV DISCUSSION... /ISSUED 644 PM CDT Tue May 23 2017/ AVIATION... Storms occurring ahead of the cold front will be moving across the terminals from 00Z at KUTS to about 04-05Z at KGLS. A strong thunderstorm should be east of KCLL by 00Z; however, more showers were developing to the west of the site. There is a slight possibility of a strong or severe storm with gusts in excess of 50 knots and large hail making its way through the sites between KCXO and KHOU between 00Z and 02Z. Expect the storms to be off the coast by 06Z. VFR conditions are then expected. Breezy winds are expected to then develop after 15Z Wednesday. 40 PREV DISCUSSION... /ISSUED 438 PM CDT Tue May 23 2017/ DISCUSSION... Surface analysis as of 1 PM CDT showed an approaching cold front stretching from Del Rio to Waco towards Shreveport, with a weak prefrontal wind shift entering portions of the Brazos Valley. Regional radar mosaic this afternoon shows a few cells developing along and behind the front as it continues to push towards the southeast. With RAP guidance instability increasing ahead of the approaching boundary and lift overspreading the region from a passing 90 knot upper jet, expect the severe weather threat to increase over the next few hours for Southeast Texas as scattered thunderstorms continue to develop along the front. Expect the front to clear the Brazos Valley late this afternoon, reaching the Houston metro mid-evening, and clearing the coast around midnight tonight. Steep mid-level lapse rates will result in a large hail and damaging wind threat (especially if any storms bow out) as the front progresses southward. A few showers may linger behind the front tonight before dissipating as drier air moves into the region, with clearing clouds and cold air advection behind the front resulting in cool overnight low temperatures in the mid 50s to mid 60s. Dry weather will continue through the rest of the week with high temperatures gradually warming into into the low 90s by Friday as shortwave ridging translates across the region. Northerly winds will gradually swing around to the south by Thursday as surface high pressure slides off to the east, allowing moisture to gradually return by the beginning of the weekend. A cold front looks to slide into Texas by the beginning of the weekend and stall at the beginning of next week as an upper low reaches the Great Lakes. Will have to keep an eye on the Monday/Tuesday portion of the forecast next week as disturbances overriding this stalled boundary look to result in a very wet period for the region. Huffman AVIATION... A cold front will push off the coast tonight with strengthening northerly winds and building seas in its wake (some thunderstorms developing along and ahead of the front could become strong or severe as they move off the coast this evening). Onshore winds will return early Thursday and quickly strengthen during the day. Elevated winds and seas can be expected from the end of the week on through the upcoming Memorial Day weekend. Caution flags will probably be needed, and advisories will be possible. 42 CLIMATE... Low temperatures Wednesday morning will be well-below normal for late May and observations across parts of the Brazos Valley and Piney Woods regions may approach or reach record low temperatures for May 24. A listing of record low temperatures for May 24 for the first order climate sites are provided below.
