The severe weather threat for Severe Thunderstorm Watch 235
SUMMARY...Severe threat continues within WW235. There is a
conditional risk across the far southern portion of the watch for
large hail, gusty winds, and a tornado or two into the evening.
DISCUSSION...A storm ongoing near Tucumcari, NM has produced 2 inch
hail along with significant wind gusts as high as 75 mph in the last
hour. Additional thunderstorm development is occurring along
developing outflow emanating from this storm across south-central
Quay and Curry Counties. Expect additional development further south
in the next couple of hours with potential for gusty winds and large
Further south in WW235, uncertainty grows with a conditional threat
through the evening. Recently, an area of more pronounced cumulus
development was ongoing across Chaves County. Surface observations
indicate that mixing has been occurring with the surface dew point
dropping into the upper 40s from the early afternoon mid 50s.
Visible satellite has shown many failed attempts at initiation
within this area and further west along the dryline. One weak cell
was able to initiate but has struggled to intensify. Day Cloud Phase
Distinction satellite imagery continues to show deepening cu with
evidence of glaciation. As the low level jet intensifies this
evening, moisture should increase along with low-level flow. If a
cell can successfully initiate in this regime and track eastward, a
conditional threat of large hail, damaging winds, and a tornado will
be possible through the evening.
