radar quiet so far this afternoon but reluctant to pull The Plug on the
mention of precipitation for this evening. We should be reaching convective
temperatures shortly.
Otherwise not a lot of changes with the going forecast of mainly afternoon/
early evening precipitation these next few days. Weak upper ridging coupled
with shortwaves from the west and this warm/moist airmass that has
settled over the region being the main factors. This pattern looks
to stick around through the weekend...possibly until the middle of
next week or so. At that time...model consensus of the upper level
flow begins to differ. European model (ecmwf) a bit slower (but stronger) with this
next upper trough than the GFS for next weds/thurs. At this time...opting to
keep with GFS as it has been verifying better of late. 41

surface high pressure located towards the east will begin to weaken
allowing winds to shift more eastwards. Low pressure in West Texas
though will allow for moderate onshore flow to continue through the
weekend. By Tuesday night the pressure gradient will begin to tighten
as low pressure forms over the southern planes. This will produce
slightly higher tides late next week. 23
