Upper level pattern is undergoing changes which will usher in an early season cold front across the area late this week.
Upper level ridge is sliding westward today with deepening downstream troughing developing over the central US. Powerful Hurricane Linda is moving NW off the west coast of Baja with its associated high level moisture clearly becoming entrained into the central US trough. Moisture levels will be on the increase on Wednesday as the frontal boundary approaches from the north. PWS will start the day in the 1.5-1.6 inch range and rise into the 2.0-2.1 inch range by early Thursday. Expect scattered showers and thunderstorms along the seabreeze mid late morning into the afternoon hours followed by more widespread and organized development later in the day in the College Station to Lake Livingston corridor.
Will see a decrease in convection Wednesday evening with the loss of heating, but likely not a complete loss of storms with the front seeping into the area. Thursday looks fairly active with short waves rotating across the area and an upper level low currently along the Louisiana coast moving W and inland over S TX. Factors will be in place for widespread storms with some threat for cell training along the frontal boundary. Very moist air mass will result in increasing rainfall rates. Front will only slowly cross the area awaiting a secondary push from an upstream trough late Friday so the area will remain under the threat for more storms Thursday night and Friday. Main threats will be heavy rainfall and high rainfall rates with some potential for flooding.
Weekend:
Front looks to clear the coast early Saturday with a significantly drier air mass moving in from the NNE. Dewpoints fall into the 50’s and 60’s on Saturday under NE winds and highs in the upper 80’s. Lows on Sunday morning will likely bottom out in the lower 60’s. The front will stall across the coastal waters over the weekend.
Early Next Week:
Highly uncertain and complicated forecast with potential for tropical cyclone formation over the western Gulf of Mexico.
Old frontal boundary will reside over the Gulf of Mexico early next week with most models in agreement on coastal troughing developing along the NE MX coast by Monday. The GFS maintains this trough in an elongated fashion into mid next week while slowly shifting it northward toward the mid TX coast…possibly closing off a 1008mb low near the coast around the middle of the week. The CMC develops a closed surface low over the Bay of Campeche in response to energy ejecting northward out of the eastern Pacific across MX. The ECMWF also forms a coastal trough, but quickly closes off a surface low and then rapidly deepens the system down to a 981mb hurricane as it tracks N then NE then ENE across the NW Gulf waters next week. The ECMWF solution is by far the most aggressive with respect to intensification. The ECMWF ensembles are starting to show development also in the western Gulf, but nowhere near the degree of the operational ECMWF.
There is enough model agreement and support to go with a coastal trough forming off the NE MX coast early next week and possibly closing off into a surface low pressure system. This line of thinking is in agreement with the latest HPC progs placing a “L” in the western Gulf. Think any tropical development will be slower than the ECMWF suggests given the very dry air mass lurking along the US Gulf coast which would likely become entrained into any circulation along with potential westerly wind shear…although the models are showing a general relaxing of the wind shear over the NW Gulf next week. For what it is worth strong warm phase ENSO years tend to favor Gulf of Mexico tropical cyclone formation and this can at times be fairly rapid.
Forecast is very uncertain for early next week with potential tropical development and any impacts along the TX coast. For now will go ahead and increase coastal winds as the pressure gradient increases out of high pressure to our NE and deepening low pressure to our SSW. This will produce a stiffening NE to ENE wind which is a favorable tidal pile-up wind for the upper TX coast due to Ekman transport (the movement of the water to the right of the mean wind direction). Will need to keep an eye on tides…even without any tropical formation as such long fetch gradient winds over time can bring higher than average tides.
