Can't rule out some embedded tstms with some heating. MVFR ceilings should gradually lift intoVFR territory outside of precip later this morning and afternoon. 47 Marine Diminishing NW winds will gradually back to the south today as TS cindy continues to move north along the tx la border today. The gradient will tighten back up during the afternoon and evening with speeds back up into small craft advisory criteria. Winds seas diminish going into the weekend. 47 Prev discussion issued 506 am cdt Thu jun 22 2017 discussion... tropical storm cindy has officially made landfall in southwestern louisiana this morning between port arthur texas and cameron louisiana. Tropical storm warnings across our area have been cancelled as of 4 am cdt. TS cindy will continue to move north at a decent clip and be over the ARKLATEX region by late tonight. Coastal winds did briefly gust to tropical storm force yesterday evening with water levels at high tide achieving 4 feet (mllw) that led to water run up debris over the brazoria and galveston county coastal roadways. Most areas along and east of i-45 picked up 1 to 3 inches of overnight rainfall with eastern chambers county recording the highest totals at slightly over 3 inches. As cindy travels north up the sabine river valley... Trailing bands of showers with embedded thunderstorms will travel in from the north and these may put down another 1 to 2 inches of rain... Locally 2 to 3 inches across more northeastern counties such as polk or trinity counties... By tomorrow afternoon. Friday's prog soundings show an early day mid-level cap that will erode once surface temperatures warm into the lower 80s. Thus this forecast calls for just slight interior rain chances. The story turns from ts cindy to the heat Friday as... With high dew points in the middle to upper 70s and a partially cloudy day... More Sun will have afternoon ambient temperatures warming into the lower to middle 90s equating to Friday's heat indices in the 104 to 108 f range. |
The weekend synoptic pattern has eastern texas placed within a height weakness channel... Or between the bermuda ridge and a northwestern mexico-centered ridge. Atmospheric column moisture will be on the rise this weekend... From around Friday's 1.8 to 1.9 inch values to over 2 inches Saturday... As steering flow transitions from the northeast to southeast. An approaching weak frontal boundary entering our very warm and humid regional environment Saturday will kick off rounds of weekend precipitation. Precipitation will be widespread... Mainly occurring during the daytime hours and be focused over the south(west)ern and central third of the cwa as well as the maritime areas (or the progged location of the highest moisture theta E axis). The enhanced lower level focus provided by this quasi-stationary boundary has weekend QPF forecast to average around an inch across southeastern texas. Mainly overcast with an easterly wind will have diurnal temperatures ranging from the very mild morning mid to upper 70s to afternoon upper 80s to lower 90s. Slightly drier weather is forecast in the extended as the daytime inland rain focus is modeled to occur along the more localized sea and bay breezes with overnight maritime rain clusters. Upper ridging hangs back to the west with a broad longwave trough positioned over the eastern conus. This will place texas in that middle ground of not being too subsident for any major drought excessive but just unstable enough to expect day to day mesoscale convective behavior. 31 Preliminary point temps pops College station (cll) 91 76 95 77 91 30 10 10 30 50 houston (iah) 86 77 92 78 90 50 30 20 30 60 galveston (gls) 85 82 89 82 87 50 20 20 20 40 Hgx watches warnings advisories Tx...

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
