Marine Weather and Tide Forecast for Nashville-Davidson, TN

SHORT TERM
(Rest of today through Sunday)
Issued at 1120 AM CDT Sat Apr 19 2025

Most of Middle Tennessee had highs in the low to mid 80s yesterday, and today is on track to add another degree or 2, especially for areas with full sunshine. There were some fairly thick clouds hanging on across our northwest counties late morning, but much like yesterday, these clouds will thin out through the afternoon. Today's record at BNA is 88 from 2006, and we will probably not break it. CSV has a record high of 83 from 2002 and we do expect that one to be broken today. Winds are breezy again today, but not quite as strong as yesterday. Gusts near 25 mph will be common this afternoon- yesterday 30-35 mph was typical.

A strong stacked high pressure center off the southeast coast will keep our wx dry and almost summer-like through the rest of the weekend. Lows tonight will be in the 60s with Sunday's highs climbing well into the 80s. The BNA record for Sunday is 87 from 2002, and that is likely to be tied or broken. CSV has a record of 84 from 1964 that is also in jeopardy. Winds will continue to be a bit gusty on Sunday as the pressure gradient remains fairly tight between the southeast ridge and a stalled front up to our northwest.

LONG TERM
(Sunday Night through next Saturday)
Issued at 1120 AM CDT Sat Apr 19 2025

For Sunday night through Monday, a low pressure system will move north northeast from the Plains to the Great Lakes. This system will get the stalled front northwest of our area moving, and that front will slide southeastward through Middle Tennessee with a high chance for rain and scattered thunderstorms. The good news is a very low threat for severe thunderstorms. CAPE values through the day Monday will increase to 300-750 J/kg over our southeast counties ahead of the front. However, lapse rates look unimpressive and the front will be rather sluggish with weak dynamics. So, there may be a couple of storms that pulse up to "strong" levels with brief gusty winds and perhaps small hail, but a low risk overall for severe wx.

The front will stall out just southeast of our area by Tuesday. We will be on the slightly cooler side of the front, but the boundary will remain near enough for a lingering low chance for scattered showers and storms.

Looking ahead, the warmth of 80s will return midweek as the frontal zone lifts north. Throughout mid to late week we will be on the northern periphery of a very warm ridge centered over the Gulf. A series of disturbances will move along this periphery bringing on and off chances for scattered showers and storms. The showers and storms will take on a diurnal pattern with the best chances each afternoon and early evening. The chance for organized severe weather looks very low, but given the warm and unsettled pattern, a storm or 2 could flare up with gusty winds in the heat of the afternoon.
