DISCUSSION

Dry and warm conditions are expected to continue this weekend as the as the mid to upper level ridge over East TX and LA continues to dominate the local weather pattern. Expect sunny to partly cloudy skies along with south to southeast winds at around 5 mph. As stated in the past few days, conditions will be warmer through early next week with high temperatures in the lower 90s for much of the inland portions and the upper 80s along the coast. Heat indices are expected to peak in the upper 90s to lower 100s through early next week. Thus, it is recommended to be proactive and be prepared for the heat if you plan to work or spend time outdoors these next few days. Drink plenty of water, take several breaks from the heat/sun, and wear appropriate clothing. Warm nights are also expected with lows rising into the mid 70s for many inland locations and the upper 70s to lower 80s along the coast. We might have high temperatures lower back into the upper 80s closer to the mid-end of the next week.

Models have "backed off" on the rain chances for Sunday night and Monday since we would still be influenced by the mid level ridge. We now have drier conditions for Sunday, and have isolated to scattered showers and thunderstorms on Monday, mainly for areas near and south of I-10. These will more likely be those afternoon storms we typically see on a hot summer day ;). Rain chances ebb in the evening as diurnal heating decreases.

Although weak disturbances are expected to pass through throughout the rest of the week, it is not known how much of the ridge will affect our local rain development. For now, it seems that we will have a rinse and repeat pattern of a few showers over the waters and coastal location during the nighttime to morning hours, followed by an increase in showers and thunderstorms during the afternoon to early evening hours as diurnal heating and instability increases. Smells like summer!
