Was a few days off and a little too aggressive with the cold front. Did deliver morning lows though! Latest CPC output is cooler than normal for the central part of the country the second half of the month. The PNA is forecasted to rise positive, this supports the cooler idea. For Texas I think we get a cold front once a week chipping away at temps slowly. Euro and GFS agrees.
CFSv2 is hinting at a start of persistent wet conditions for the state starting late this month. Analogs point to this scenario. The 5h pattern for North America is shifting into an EPO-/-AO configuration later this month. This should translate into a likely wet/cold October.
The PNA did not rise as positive and in fact was slightly negative side of neutral. This probably aided in the week-long heat just after mid-month which in fact was impressive. The current weather coincides with the shift of EPO and has begun the wet/cooler period.

Heading into first half October, CPC is showing below to much below average for the middle of the country. The models (ensembles included) favor the EPO to go very negative which should translate into a +PNA for much of this period. We should look for passage of a very potent cold front by next weekend into the following week. Probably chilliest and most fall-like air mass of the season. Analogs suggest a wet and cold October, so following what happens this month is crucial both in terms of cold air and storm patterns.
So far this fall, I have noticed the storm track through Texas has been west to east versus the usual Panhandle hooker that swings up into the midwest. This is the reason we have been lacking severe weather. Instead we get a few days of wet/cool via slow moving upper lows. Is this a trend? I sure hope so for winter's sake for the eastern half of the country (gulf lows anyone?).
