...SCATTERED SHOWERS AND THUNDERSTORMS ALONG THE TEXAS COAST WITH INCREASING CHANCE OF MONSOONAL SHOWERS IN NEW MEXICO...

A very slow eastward progression of the center of the upper level high pressure dome will begin over the next couple of days. A steady increase in the amount of shower and thunderstorm activity can be expected through the weekend for much of New Mexico.

Tonight and Saturday morning another complex of storms is expected to develop across parts of KS and OK once again. However, the flow aloft is expected to become more westerly as the upper ridge begins to build across TX. This flow is expected to supply enough atmospheric moisture to allow for spotty convective activity from the Wichita Falls area down to Del Rio hitting the western portions of the Hill Country this afternoon. Scattered isolated thunderstorms will continue along the coast from the sea breeze as well, all of which are not expected to generate any flooding. Scattered isolated thunderstorms will also continue along the coast from the sea breeze which is not expected to generate any significant flooding.

By Sunday the upper ridge will begin redeveloping directly over the Southern Plains. This will effectively bring an end to our rain chances in Texas for several days. Monsoonal activity over New Mexico and Southern Colorado is expected to continue on a limited basis as the ridge will limit the higher rain producing monsoonal activity.



...PRECIPITATION FORECAST...

Day 1: 24-Hour Rainfall Total Day 2: 24-Hour Rainfall Total

For Today into Saturday morning, no significant Mean Areal Precipitation (MAP) amounts are forecast for the WGRFC area.

For Saturday into Sunday morning, MAP amounts of 0.25 to 0.50 of an inch are forecast for portions of New Mexico mostly isolated to the Rio Grande valley and along the Texas southeast coastal basins.

Day 3: 24-Hour Rainfall Total Day 4-5: 48-Hour Rainfall Total

For Sunday into Monday morning, MAP amounts of 0.25 to 0.50 of an inch are forecast for portions of New Mexico mostly isolated to the upper Rio Grande valley.

For Monday into Wednesday morning, MAP amounts of 0.25 to 0.50 of an inch are forecast for portions of the western half of New Mexico mostly isolated to the upper Rio Grande valley.

5 Day Total Rainfall Forecast

Soils continue to dry out across Texas due to the warm temperatures and a lack of significant rainfall. The U.S. Drought Monitor has categorized Texas as 13% abnormally dry, with almost 2% in moderate or greater drought. Over New Mexico, 77% of the state is abnormally dry, and 16% remains in the moderate drought category. Some rainfall is forecast over the next five days primarily over east and southeast Texas and western Louisiana. This will keep drought conditions from developing in this region, but only minor runoff is anticipated. The lack of heavy rainfall elsewhere will lead to continued drying through this forecast period and no significant runoff is expected.
