A progressive upper level pattern to usher through a family of 500mb troughs moving rapidly west to east across the country bringing at least two cold fronts through the long-term and possibly a 3rd front next Tuesday. Models remain in good agreement and consistency with this fast upper level synoptic flow pattern.
The first trough and front move through Wednesday morning, slower than previous models, due to the trough closing off for about 12 hours. The front brings with it a chance of showers with still a slight chance of thunderstorms which should move off the coast in the morning with some linger showers in wake of the boundary as the upper trough opens up and lingers over the Red River along TX/OK border. Modest drier and cooler air to filter in quickly with temperature initially trending lower than showing limited recovery for the afternoon. As for fire weather threat the cooler ambient temperatures and not as low dewpoints to keep relative humidity levels higher than previous model runs. Gusty winds in the morning could briefly elevate fire weather concerns west of I-69C, however northwest winds drop through the afternoon lessening the threat for red flag conditions. A cool Wednesday night and mild fair weather day is expected Thursday as weak high pressure settles over the region.
Next short wave dives quickly south along the front range of the Rockies Thursday moving across Texas Thursday night/Friday morning. A slighlty stronger cold front is still indicated to sweep through with gusty wind and much drier air Thursday night. Dew points and relative humidity likely to be the lowest of the week while initial wind conditions may be elevated models show gradual lowering of the winds for the afternoon. Fire weather conditions are likely to be elevated but with the lowering winds Red Flag conditions may be waning, but we will continue to monitor. Mid-level high pressure builds over the state through Saturday with Temperatures below normal temperatures Friday and Saturday with lows in the 30s and 40s and highs only in the 60s. Fair weather continues Sunday but as surface ridge heads east winds turn southeast ushering in a warming trend. Monday the region may see the south winds increase to strong levels in advance of the next strong low pressure trough with models showing this the strongest and farther south of the series of troughs this week.
