Inconsequential Light Rain/Snow Mix Possible Thursday Morning

Up to 51° Wednesday afternoon. No rain. All eyes on Thursday morning when a band of light, cold rain mixed with snow should move in. It will arrive Thursday morning and there will not be much of it. Best rain/snow mix potential is in Will Co but although less likely in Nashville, it’s possible in Nashville. We may not see any precip at all because the system is weak and passing mostly south of us. read more

Severe Threat Over, Flooding Concern Remains, Much Colder Next Few Days.

Our severe weather risk is over, but flooding concerns remain. NWS-Nashville issued an Urban and Small Stream Flood Advisory for the middle of Nashville through 8:45 PM.

Light rain will linger then end sometime before midnight. We’re watching local creek and river gauges and will tweet any flood warnings issued by NWS-Nashville. It can take hours for flooding to occur. read more

Still gross Sunday morning (34°), bit warmer Sunday afternoon (51°) but still cloudy. Then light rain Sunday night.

NAM3 model Sunday night.

We do the mornings 30°s, afternoons mid/upper 40° thing next week. Precip possible but iffy Tuesday night into Wednesday (low water content) and again Friday (as usual models vary substantially).


Snow isn’t found in Euro Ensemble model data thru 2/9/20. The slope rises toward the end of that time frame but that’s been happening all winter in this product and no one has used a sled.

2. Winds gusting to 30-35 MPH this morning should relax this afternoon.

3. Cold front tonight. You need a jacket. Wind chills will drop below freezing around 9 PM.

Be thunderstorm-aware today.

One weather model, the HRRR, thinks heavy rain and thunderstorms will arrive around 4 PM (give or take a few hours).

The HRRR model thinks these storms may be strong or severe, however, this model may be overstating the severity of the storms (below see HRRR model which expects 1,161 j/kg of surface based CAPE to fuel a pretty big storm or two; this high amount of storm fuel seems unrealistic given the cloud cover, so HRRR may be predicting the storms to be worse than they’ll actually be). read more
