FREEZE POTENTIAL: Saturday and Sunday morning we could see areas reach or go below 32 degrees. These temperatures could kill sensitive vegetation so be sure to protect them this evening.
SATURDAY: High pressure will move back into the Valley and give us mostly sunny skies. Temperature will stay cold with highs only around 50.
SUNDAY: Temperatures rebound back into the 60s with sunny skies.
WET PATTERN NEXT WEEK: We will see a couple of systems that could bring in some rain and storms. Monday a weak front will pass through during the morning and cause some showers. Another weak system could bring in more showers Wednesday and Thursday. A cold front Friday could bring in rain and storms. The storm threat looks non-severe right now.
A FREEZE WARNING HAS BEEN ISSUED FOR THE TENNESSEE VALLEY FROM 1 A.M. TO 10 A.M. SATURDAY MORNING AS TEMPERATURES WILL BE FALLING BELOW THE FREEZING MARK.
IN ADDITION, A HARD FREEZE WARNING IS ISSUED FOR WAYNE, GILES, AND LAWRENCE COS. TN WHERE TEMPERATURES WILL BE AT OR BELOW 28 DEGREES SATURDAY MORNING.
COLD END TO WEEK: A strong Northwesterly flow of winds will continue to keep the chill in the air. Huntsville experienced a 33 degree drop from 77 at 1 P.M. Thursday afternoon down to 44 degrees this morning. Clouds will clear out and we'll see some sunshine today, however, temperatures will barely make it into the mid 50's. By this evening, there is a chance of graupel, also known as soft hail, from a weak wave of energy. What is graupel? Very cold conditions move in from the North, causing upper level temperatures to reach near -30 to -40 degrees Celsius or -22 to -40 degrees Fahrenheit. When this happens, supercooled liquid in a cloud (liquid that stays as a liquid below the freezing mark) collides and sticks onto falling snowflakes within the cloud. When they combine, they create soft hail or graupel. It's a rare event for the Tennessee Valley as we usually never get this cold! Graupel is non-damaging, and is white in color as oppose to hail. In addition, hail occurs in warm weather events and graupel occurs in cold weather events.
TONIGHT: By tonight, we'll clear from this system to cause the Valley to drop into the upper 20's to lower 30's.
SATURDAY: On Saturday, we'll barely make it to 50 degrees with a mix of sun and clouds.
SUNDAY: Southerly winds return and we rebound back into the lower 60's for temperatures.
FREEZE WATCH: The potential is there for a freeze Saturday morning. This is for Saturday 1 a.m. until Saturday 10 a.m. for Wayne, Lawrence and Giles Counties in southern Tennessee. Be sure to protect sensitive vegetation before this time.
A FREEZE WATCH MEANS SUB-FREEZING TEMPERATURES ARE POSSIBLE. THESE CONDITIONS COULD KILL CROPS AND OTHER SENSITIVE VEGETATION
A strong cold front will sweep across the Tennessee Valley this afternoon.
THIS MORNING: Ahead of this cold front, this morning we'll be waking up to temperatures into the mid 60's with mostly cloudy skies. A few stray showers may develop this morning.
THIS AFTERNOON: The heaviest batch of rain showers associated with this cold front will move into the Shoals as early as Noon-1 P.M. and slide eastward throughout the afternoon time. The rush hour commute back home from work will be sloppy, with possible heavy rain showers and a couple rumbles of thunder. Make sure to have the umbrella ready to go! Temperatures will climb into the mid 70's for highs before the rain moves in. Possibly on quarter of an inch of rain could accumulate.
TONIGHT: Isolated showers will continue until midnight, then we'll see a Northwesterly wind begin to cool us down as skies clear. Temperatures will fall into the mid 30's with breezy conditions. It's going to be very chilly come Friday morning.
THURSDAY: We are starting off the morning warm with only some widely scattered showers. The front should be pushing through the Valley between noon-4 p.m.. The front will create chances for showers and some isolated storms. Any storms that form would be non-severe. Winds will become breezy at times during the afternoon and evening. Temperatures will also take a quick hit once the front passes due to colder and rain cooled air.
WEEKEND: The weekend will be fairly sunny and dry but the mornings will be on either side of 32°. Temperature will rebound Sunday with highs in the 60s.
POLLEN COUNT: Even with the expected rain it won't do much to budge those numbers.
LAST WARM, SUNNY DAY: Wednesday will be our last day of this beautiful stretch of weather we've been seeing this week. Temperatures will climb into the upper 70's with a mix of sun and clouds. Winds will be breezy at times during the afternoon hours.
THURSDAY'S WOES: A very strong cold front will march through the Valley come Thursday afternoon, giving us a round of isolated showers and thunderstorms to deal with along with gusty winds. Thunderstorms will be non-severe, but a big drop in temperatures will come our way by Thursday night as winds turn in from the Northwest. We'll drop from the lower 70's to the upper 30's for Friday morning.
WEEKEND COOL DOWN: Temperatures heading into the weekend will be effected from a Northwesterly flow of winds. Although we'll see plenty of sunshine, we'll be about 10 to 15 degrees below average for this time of year. Temperatures will remain into the mid to lower 50's and overnight lows right near the freezing mark. Yikes, our first Freeze Watch might be issued as we head closer to the weekend.
WEDNESDAY: Temperatures will warm easily into the 70s but sadly this will be our last day in the 70s for a while. A stay shower is possible but not likely.
THURSDAY: A cold front comes through Huntsville around noon. Scattered showers are possible before and after the front. Before the front we could hear some thunder if a few cells become a little stronger.
TUESDAY & WEDNESDAY: Southerly winds will continue to bring in the warmth as temperatures will soar into the mid to upper 70's for Tuesday and Wednesday. This warmer air is being pulled in ahead of an approaching strong cold front. As winds turn in from the Southwest come Wednesday, more moisture will be pulled in from the Gulf to cause a few stray showers to form over Northeast Alabama. The rest of us will stay dry until Thursday.
COOL AIR RETURNS THURSDAY-WEEKEND: A strong cold front will swing through the Valley, allowing for isolated showers and a few rumbles of thunderstorms to develop, along with breezy conditions. We'll see our temperatures go from the upper 70's to the lower 50's come Friday. In fact, Northwesterly winds behind this cold front will even dip our overnight lows down to the freezing mark come this weekend. Brrrr! We'll have to be on the lookout for a possible freeze/frost advisory come this weekend, sadly.
TONIGHT: Skies will be mostly clear but after midnight we will cool off enough to have fog develop.
TUESDAY: Temperatures will be above normal with mostly sunny skies.
NEXT FRONT: Our next front will arrive Wednesday night and linger through Thursday. Only some scattered showers will be possible.
MONDAY-WEDNESDAY: As lower pressure over the Gulf pushes over Florida, we'll start to see more sunshine today! Sunshine is in store for West of I-65, with partly sunny skies East of I-65. Everyone will be back to sunshine come Tuesday and Wednesday, and with southerly winds returning, we'll be into the 70's!
THURSDAY: A cold front will slide in late Wednesday night, allowing for a few showers and possibly a couple rumbles of thunder Thursday. It'll be breezy with winds moving in from the Northwest 10-20 mph. That Northwesterly winds will cool us down into the 60's on Thursday and 50's come Friday.
FRIDAY-WEEKEND: Speaking of the weekend, with cooler air in place, temperatures will fall into the 50's with mainly clear skies. This also means we'll dip into the lower 30's, where a possible freeze/frost could occur. Farmers and gardeners beware!
