AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
A moist and tropical air mass is in place across our area as a tropical
disturbance, and its counter clockwise rotation, has made landfall over
Mexico south of the Brownsville area as it moves north northeastward
more or less moving parallel to the northern Mexico and south Texas
coast. This is occurring as a weak cold front edges southward into central
Texas. As a result, scattered to numerous rain showers are expected
today into tomorrow with the possibility of periods of heavier rain given
very high atmospheric moisture content and very efficient tropical
rainfall rates. Flood watches have been issued all along the Texas coast
and as far north as central Texas and the Waco area. For the IH35 corridor,
the flood watch is in effect until 7pm Tuesday evening.
In a lower confidence forecast, there appears to be a bit of a break in the
precipitation for the IH35 corridor by late Tuesday into early Thursday
although it will highly depend where the weak tropical disturbance tracks.
If it tracks more inland and closer to our area, I’ll have to increase rain
chances locally but, on the other hand, if it tracks more eastward, which
is what we’re thinking now, the break in the precipitation is indeed likely
to occur. Stay tuned for later updates.
Another weak low pressure disturbance looks to approach our area from
the west and northwest by late Thursday through next weekend with rain
and storm chances returning to our IH35 corridor forecast.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– High to very high forecast confidence through Tuesday..
– Medium to high forecast confidence Tuesday night through Sunday..
