FIRST ALERT WEATHER: Clouds are back Wednesday, few showers too; Rain/Thunder arrive Thursday AM

COLUMBIA, S.C. (WIS) - The clouds are back Wednesday and we see some afternoon showers too (30% chance). Then heavier rain and even some thunder is possible especially Thursday morning.

FIRST ALERT HEADLINES

• More clouds move in tonight with lows in the mid to upper 30s.
• Cloudy skies and cool temperatures Wednesday with highs in the low 50s.
• 30% chance of rain showers Wednesday afternoon.
• Chance of rain goes up to 90% overnight Wednesday into Thursday morning.
• Rain is extremely likely Wednesday night into Thursday, with local amounts as high as 1″ possible.
• We cool off and clear up Friday with highs in the mid 50s with mostly sunny skies.

FIRST ALERT SUMMARY

Tonight we see temps in the upper 30s with more clouds building out of the south.

Southern flow aloft will transport moisture from the Gulf over some cooler air Wednesday. This leads to a cloudy day with highs in the low 50s. Expect a 30% chance of showers by the afternoon as moisture streams in. High temperatures are near 51, so much colder than average.

Thursday we are warming up as the southern flow increases and highs reach the mid 60s. This moisture brings a 90% chance of rain as a cold front nears from the west. The best chance of rain looks to be in the morning. There’s even a marginal risk of severe weather, (level 1 lowest risk) for areas south and east of I-20. I’m really thinking we will just see some rumbles of thunder throughout the morning hours as the front passes through the most stable part of the day (early morning).

Some areas to our north could see around 1″ of rain but it looks like around 0.25-0.75″ for areas south.

The cooler and drier air rushes in behind the front and we have temps tumbling down to 38 by Friday morning. Expect mostly sunny skies Friday with high temperatures in the mid 50s.

The weekend looks dry and cool. Saturday has partly cloudy skies with lows in the mid to upper 30s and high temps near 50. We see sunny skies Sunday with highs near 50 and morning lows closer to 32.
