Blog: Rain Moves In. Potential For Flooding.

FUTURE TRAK WIDE FRI EVE_1544794655227.png.jpg

We just had a stretch of colder/drier weather for a few days.  Yesterday we warmed up a little bit.  However, a warm front will move into the region today.  That will eventually pump in some even warmer air, but the moisture is also pumping in.  High pressure is moving farther offshore.  At the same time an area of low pressure is developing over Louisiana.  It is moving steadily east. 

There is a lot of rain to the east of the low.  Basically….here we go again….It’s overrunning.  So the warmer/more humid air is pushing in at the mid-upper levels.  It’s riding over a cooler airmass at the surface, and this is forcing condensation to occur.  We are pretty dry at the surface this morning, but eventually the moisture will win out.  We have a warm front that is slowly going to move in from the southeast.   Despite lots of clouds, we’ll warm up to the upper 50s to low 60s this afternoon.  However, the rain showers will move in between the midday and mid-afternoon.

The coverage will increase between the late afternoon and evening.  Then we’ll have widespread rain overnight.  Tomorrow the area of low pressure will move through the region.  It will pull in lots of warm/humid air.  So high temps will be in the mid 60s, but you won’t get to enjoy it.  Rain will be on and off through most of the day.  It could be heavy at times tonight and tomorrow.  So there is a Flood Watch up for most of the region. 

I don’t think we’ll see too much street flooding actually.  However, I do think we’ll see flooding on many of our rivers and streams.  We have had a lot of rain recently.  So many of the waterways are already elevated.  Therefore, the forthcoming rain could push some of the rivers up to moderate flooding levels.  They could crest after the storm departs.  Stay tuned.

On Sunday the low will slowly move offshore.  However, the upper level low will linger behind it.  So we’ll have some scattered showers in the morning. Then showers will be more isolated by Sunday afternoon.  High temps will still be near 60.  We’ll be drier and mild on Monday with highs again near 60.  However, colder air will briefly move in on Tuesday.  Highs will be in the 40s. 

For rain totals.  We may get about 1 – 2″ of rain between this afternoon and Sunday. 

Again…these amounts don’t typically cause problems by themselves.  However, factoring in the recent rain, it could cause some flooding in low-lying areas near the water.  The wind won’t be strong enough for any tidal flooding. So that will help some. We’ll be tracking all it through the weekend.
