Highs this afternoon will be in the lower to mid 60s in the central and southern TN Valley, with mid to upper 50s elsewhere. Cooler temperatures today and tonight. Given how dry it has been/the low RH's currently, and the pretty isolated to scattered nature of the showers, don't expect rainfall amounts of more than a tenth or so. Highs today expected to be 10-15 degrees cooler than yesterday or so with the lower heights aloft and cloud cover.
549 AM CST Thu Feb 27 2025 - Slightly cooler, but still mild, conditions continue with highs in the 60s. This combined with a small ridge to the west continues the NW flow over our area keeping skies dry and temperatures relatively subdued. A strong low pressure follows the wake of the initial push of Canadian air. Combined with a bit of ridging and diurnal mixing leading to wind gusts around 20-30 MPH, high temperatures Friday push into the upper 60s to near 70 degrees. As the low traverses the Great Lakes Friday afternoon, winds turn back northwesterly over the MO River Valley restarting the cold air advection.
330 AM CST Thu Feb 27 2025 - Slightly cooler, but still mild, conditions continue with highs in the 60s. This combined with a small ridge to the west continues the NW flow over our area keeping skies dry and temperatures relatively subdued. A strong low pressure follows the wake of the initial push of Canadian air. Combined with a bit of ridging and diurnal mixing leading to wind gusts around 20-30 MPH, high temperatures Friday push into the upper 60s to near 70 degrees. As the low traverses the Great Lakes Friday afternoon, winds turn back northwesterly over the MO River Valley restarting the cold air advection.
(Rest of Today) As an upper level trough and accompanying cold front continues through the area and into the Appalachian region, NVA takes over the Tennessee Valley and dry weather continues. Current cloud cover should begin to clear out from northwest to southeast this afternoon with the frontal passage, bringing highs into the low to mid 60s.
Rain has already moved east of the Ohio River and will continue to progress east along with the cold front this morning. Rain will continue moving through the area in concert with a cold front early this morning. While rain remains the dominant precipitation type for the lowlands, temperatures are expected to cool enough to support snow over the higher terrain.
A very brief period of skinny sfc ridging moves through overnight before the next clipper dives toward wrn Lake Superior by 12Z. Can't rule out some slick spots developing overnight as temps fall below freezing. - Windy Friday and Friday Night Tight pressure gradient associated with this next system tracking through the nrn GrtLks Rgn leads to windy conditions on Friday, augmented by deeper mixing in the mild air preceding the attendant sfc cold front. The highest potential for wind gusts reaching advisory criteria around 45 mph Friday looks to be south and east of Grand Rapids where the warmest temps and better mixing are expected away from the cooling effects of Lk MI. Since the low level jet appears to moving away just as the deeper mixing is developing, will hold off on a wind headline at this time.
(Tonight) Skies have cleared through most of the area in the wake of the cold frontal passage with the exception a few cirrus clouds as dry air continues to filter into the area from the northwest.
Cooler highs are in store today, with most areas peaking in the lower 60s to lower 70s. A very gradual decrease in mid and high level clouds is anticipated overnight, with low temperatures ranging from near 40 in the Hill Country to the lower 50s along the Rio Grande.
A zone of confluence that we have been tracking since yesterday afternoon progressed from the Straits of Florida northward to the Lower Keys earlier this afternoon. Temperatures range from the lower to mid 70s in Key West to near 80F in portions of the Middle and Upper Keys that have seen ample solar insolation. Synoptic surface analysis places a weak cold front stretching from the western Gulf northeastward to the Appalachians of the Carolinas. Weak high pressure building in the wake of the front will promote northerly breezes for Friday through the weekend along with nil rain chances.
As surface ridging quickly shifts across the Gulf Coast, winds shift back on-shore from the southwest, gradually rebuilding surface moisture. Clear skies and maximized insolation will allow for above normal temperatures to return tomorrow with temperature maximums/minimums back in the lower 70s/lower 50s, respectively.
1154 AM CST Thu Feb 27 2025 Visibilities continue to improve across the coastal plains as a cold front moves through this region. (Today through Friday) Key Messages: - Cooler temperatures along with gusty northerly winds expected today. A cold front will make quick progress southward this morning, bringing with it gusty northeasterly winds and possibly a shower or two over the Coastal Plains.
1117 AM CST Thu Feb 27 2025 - Slightly cooler, but still mild, conditions continue with highs in the 60s. This combined with a small ridge to the west continues the NW flow over our area keeping skies dry and temperatures relatively subdued. A strong low pressure follows the wake of the initial push of Canadian air. Combined with a bit of ridging and diurnal mixing leading to wind gusts around 20-30 MPH, high temperatures Friday push into the upper 60s to near 70 degrees. As the low traverses the Great Lakes Friday afternoon, winds turn back northwesterly over the MO River Valley restarting the cold air advection.
314 PM EST Thu Feb 27 2025 - A cold front will move through the area early this morning with a few showers.
258 PM EST Thu Feb 27 2025 Cold front will continue to move southeast of the area this evening.
A strong area of high pressure aloft will maintain the dry conditions, light winds, and mild temperatures today.
1110 AM CST Thu Feb 27 2025 (Rest of Today) As an upper level trough and accompanying cold front continues through the area and into the Appalachian region, NVA takes over the Tennessee Valley and dry weather continues. Current cloud cover should begin to clear out from northwest to southeast this afternoon with the frontal passage, bringing highs into the low to mid 60s.
In the wake of the weak dry cold front high pressure will continue spread into the region from the west/northwest, this will cause skies to clear throughout the afternoon. Temperatures will cool slightly but will be enough to make a noticable diffecence with todays high temperatures limited to the the mid 60s to lower 70s while overnight low temperatures cool down to the lower 40s. Ridging will be prevelant Friday as dry conditions and sunny skies return with temperatures warming into the upper 60s to lowers 70s.
Light showers in SW VA tonight with a passing trough. Discussion: A dry low level air mass will continue to build into the area behind the exiting cold front through this evening. After sunset, a mid/upper level trough will cross the Appalachians. Colder temperatures aloft under this trough will create steep lapse rates that may be able to squeeze out enough moisture for measureable precip in parts of SW VA. Through Friday, we will have a nearly zonal flow aloft with high pressure over the TX extending across the Deep South and a low pressure system over the Great Lakes.
(Now through Friday Night) An upper-level trough, currently extending from the Great Lakes to the Tennessee River Valley, will continue to dig to the southeast through the remainder of the day today. This trough will exit into the western Atlantic by late tonight. A second upper trough follows in its wake, setting up over the northeast US by the end of the period. At the surface, a cold front currently bisects our local area, generally along the I-65 corridor. In the wake of the front, high pressure building in from the west will allow for a much drier (and slightly cooler) airmass to move in. With clouds clearing out, lows for both tonight and tomorrow night will drop into the low to mid 40's, with upper 40's along the immediate coast. Highs tomorrow will top out in the low to mid 70's.
Ridging will bring dry weather with above normal temperatures.
345 PM EST Thu Feb 27 2025 High pressure will nose into the region tonight, offering dry conditions. Upper trough swinging through the Great Lakes and Ohio Valley will exit to the east tonight. High pressure will nose into the region late from the southwest, allowing winds to slacken and clouds to decrease. Temperatures will dip into the low 30s. The ridge of high pressure will push off to the east of our area on Friday as a fast-moving cold front approaches from the northwest. The cold front will slice through the area Friday night.
High pressure will produce warm, dry conditions with light winds for the next couple days. Temps will inch a few degrees warmer on Friday with low 40s in the upper Snake Plain, mountains and highlands, to low 50s in the eastern Magic Valley.
By this evening, cooler and drier air will filter in behind the boundary, allowing our daytime temperatures in the mid-70s to cool to the low to mid-50s overnight. A weak warm frontal boundary will left northward into the region on Friday, shifting winds back to a more easterly direction by end of day.
pdf A cold front is poised to make its way through the area from the northwest to the southeast in the late afternoon. Mostly clear to partly cloudy skies with high daytime temperatures in the upper 70s to low 80s over the area with temperatures staying slightly cooler along the coast.
1137 AM CST Thu Feb 27 2025 (18Z TAFS) A scattered to broken cloud deck around 2000 to 3500 feet will continue to slowly erode over the course of the afternoon as a cold front moves through the area. High temperatures today and Friday will be in the lower to middle 70s. Lows tonight cool slightly in the wake of the front, ranging from the low to mid 40s across most of the area, and upper 40s to around 50 along the immediate coast. Lows Friday night will be about 2 to 3 degrees warmer compared to tonight.
926 AM CST Thu Feb 27 2025 Visibilities continue to improve across the coastal plains as a cold front moves through this region. (Today through Friday) Key Messages: - Cooler temperatures along with gusty northerly winds expected today. A cold front will make quick progress southward this morning, bringing with it gusty northeasterly winds and possibly a shower or two over the Coastal Plains.
We have had a ridge of high pressure over us the past few days leading to warm afternoons. This ridge has led us to look out for records to be broken today in the Valley. Bakersfield has the highest probabilities as they are going to see strong southeasterly gusts from the Tehachapi Mountains this afternoon.
GOES-16 visible satellite imagery highlights a zone of confluence over and south of the Lower Keys, with associated mostly cloudy conditions. From synopsis, high pressure over the Gulf Coast will slide into the western North Atlantic this afternoon, resulting in generally light east to southeast breezes becoming variable at times. A weak cold front will push through the Keys coastal waters tonight, with another area of high pressure building in the Gulf for Friday through the weekend.
