Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 1100 PM CST Mon Nov 27 2017 ...06z Aviation Update... DISCUSSION...Updated for latest aviation discussion below. && .AVIATION...VFR conditions will prevail through the overnight hours and until around sunset Tuesday evening. Clear to mostly clear skies with light winds are expected under the influence of surface and mid- level high pressure. MVFR may creep into the forecast after sunset Tuesday evening with some lowered cloudiness developing. && PREV DISCUSSION... /issued 150 PM CST Mon Nov 27 2017/ SHORT TERM (Tonight through Tuesday Night): A broad area of strong mid/upper level high pressure over much of Mexico will maintain a dry west to northwest flow aloft over deep south Texas through the period. At the low levels, weak southeasterly onshore flow will prevail. Fair weather is expected through the short term with a mostly sunny day Tuesday and mostly clear nights on either side. Surface dew points are slated to slowly increase over the next 24-36 hours with patchy fog possible for many locations early Tuesday morning as a weak cold front approaches from the north. Overnight lows both nights will generally be in the upper 50s out west and over the northern ranchlands with lower 60s elsewhere, though lows Tuesday night/Wednesday morning may be one to three degrees higher than Tuesday morning's lows. Highs Tuesday afternoon will be similar to high temperatures reached today and should generally range from the upper 70s at the coast with lower to mid 80s inland. LONG TERM (Wednesday through Monday): A short wave trough moving over Oklahoma will push a weak cold front through deep south Texas on Wednesday. High temperatures Wednesday and Thursday will be in the upper 70s to the lower 80s with light northeast winds. Low temperatures Wednesday night and Thursday night will be in the 50s inland and around 60 along the coast. Mid level ridging remains generally in place over Mexico through late week. Another surge of high pressure upstream pushes east into the Plains Thursday bringing another weak cold front into the region Thursday night. High temperatures Friday will be in the mid to upper 70s with abundant sunshine. Surface high pressure will shift east Friday into the weekend, as the mid level ridge moves more overhead. Southeast flow Saturday through Monday will bring some moisture into the area resulting an increasing cloud cover this weekend. Above normal temperatures will continue through the weekend. Generally rain free conditions expected across deep south Texas through the forecast period. MARINE (Tonight through Tuesday Night): Weak persistent southeasterly onshore flow will maintain modest winds less than 15 knots and seas around two feet through the period. Wednesday through Saturday night: Light to moderate generally north to northeast winds will prevail through the period as high pressure settles across the region. Low to moderate seas will continue Wednesday through Saturday night with no small craft advisories expected. && .BRO WATCHES/WARNINGS/ADVISORIES... TX...None.
