A FLASH FLOOD WATCH is in effect for every county in SW AR and E TX along and south of I-30 and all of NW LA through Noon on Saturday. Widespread rainfall totals in the watch area through Saturday will likely between 3-6″ of rain. There is a Moderate Risk of excessive rainfall for most of E TX south of I-20 and the western half of NW LA. The greatest threat of heavy rainfall and flash flooding will be late this evening through early Saturday.
As the main energy associated with the upper-level storms system swings through, more heavy rain will develop and push from west to east tonight through Saturday morning. This is when the threat of excessive rainfall and flash flooding will be the greatest. With the potential of flash flooding occurring overnight make sure you have a way to get weather alerts overnight. Also, be careful traveling. It is very dangerous to drive through flooded roadways. Plus, flooded roadways can be hard to see at night.
Heavy rain could dampen the start of the weekend. The best chance for heavy rain Saturday morning will be across NW LA and SW AR. The heaviest and widespread rain will be well east of the area by Saturday afternoon. However, scattered wrap around showers will be possible Saturday afternoon and evening. If the rain lingers long enough, a few snow flakes could mix in Saturday evening or night, mainly along and north of I-30. Highs on Saturday will only be in the mid to upper 40s.
Sunday will be the better half of the weekend. Even though it's going to be chilly, most will stay dry. The clouds will even start to breakup Sunday afternoon and evening. Highs on Sunday will be in the mid to upper 40s.
The start of next week looks sunny and cool. Highs on Monday and Tuesday will be in the low to mid 50s. Monday morning and Tuesday morning will be cold, though. Most will wake up to temperatures near freezing on Monday and Tuesday. The middle of next week will be warmer. Highs will be near 60 degrees on Wednesday and Thursday. Our next chance of rain will be towards the middle or the end of next week.
Have a great night and stay dry!
