Texas Fire Potential Update
October 26th through 31st • Increasing dewpoints and RH in east Texas will slow initial attack activity but will only temporarily reduce fuel dryness. • Increasing initial attack activity in the western High Plains Saturday through Monday with persistent elevated fire weather. • Please stay current with local NWS fire weather forecasts for changing conditions with an active weather pattern 14 Day Observed Rainfall Rainfall over the last 14 days has been associated with two frontal passages. Duration for this rainfall has been short with the fast moving systems. There is little chance for rainfall for the next 5 days. Gulf moisture may bring increased chances to eastern Texas late next week. Rainfall forecast through Monday AM 60 Day Percent of Normal (PON) Rainfall 25% of normal rainfall deficits are beginning to show in the 60 day period. This time frame provides better guidance for areas of increased fire activity during the fall and winter months when daily drying potential is reduced due to shorter days and cooler temperatures. Northeast Texas still leads the way but the eastern half of Texas continues to build 25% of normal rainfall deficits. Oct 25th 30 day PON rainfall October 25th Statewide ERC trends are now trending above normal. Dry conditions for the next 7 days for most all the state should continue to increase ERC values. Higher RH in east Texas will hold ERC values below the 90th percentile http://ticc.tamu.edu/Documents/PredictiveServices/Fuels/erc_map.htm Fuel Dryness Increased dewpoints and afternoon RH will continue to moderate 100 hour fuel moistures in eastern Texas and hold Fuel Dryness in the normal range. RH and dewpoints will be decreasing along the western Plains and particularly in the western High Plains Friday through Monday. Expect Fuel dryness to increase to dry levels for the western high Plains. It may be possible to reach critical dryness by Monday afternoon at a few locations. Minimum RH forecasts for Friday (28th) and Monday (31st) Dry air begins to push into the western Plains on Friday Monday Dry air persists in the western Plains and Gulf moisture persists in the eastern half of Texas Tuesday Forecast prefrontal conditions on the High Plains Monday afternoon could increase initial attack activity in the above normal load, transition stage grasses Surface forecast for Monday AM Forecast Wind at 1300 Monday
