Updated Aviation Discussion


* Southwest winds will gust 25-35 mph today, especially this afternoon.

* The gusty winds combined with filtered sunshine and temperatures rising into the lower and middle 70s may lead to slightly increased fire danger this afternoon in exposed areas where fuels can lose moisture.

* Light rain showers this evening and tonight, especially along and north of I-64.

* Lows in the 30s Wednesday night from southern Indiana into the northern Bluegrass region, and typical cold spots.

* Active weather Friday through the weekend, but plenty of uncertainty in timing of any intervals of showers and thunderstorms.

* Weekend will feature temperatures in the 80s and breezy southerly winds.

Southwest winds between low pressure over the Great Lakes and high pressure over Georgia and South Carolina, combined with sunshine filtered through high clouds, will bring us a warm and breezy spring day today. Winds gusting 25-35mph this afternoon will help to push temperatures into the lower and middle 70s.

The low to our north will advance along the St Lawrence River tonight and drag its trailing cold front through the Ohio Valley.
The front will be weakening as it passes through and will have only a narrow band of moderately enhanced atmospheric moisture pooling along it, mostly in the mid and upper levels. Instability continues to look meager. So, a band of showers, mostly light, is expected to enter southern Indiana from the north by early evening and proceed southeastward across central Kentucky tonight, ending by the time the sun comes up tomorrow morning. General rainfall amounts over southern Indiana around a quarter to a third of an inch will diminish to less than a tenth of an inch in southern Kentucky.

Despite the cold frontal passage, low temperatures by dawn will only fall to the upper 40s in southern Indiana and to the mid 50s in southern Kentucky, with colder air well behind the front over the upper Great Lakes closer to a dome of Canadian high pressure over Ontario.

===== Wednesday - Thursday =====

Dry weather is expected for our Wednesday and Thursday as sfc high pressure slides across the Great Lakes. Temperatures will be near normal for this time of year, with highs on both days on either side of 70F. For areas north of the Ohio River and in the Bluegrass region, temps could perhaps be a few degrees cooler where cloud cover may linger into the afternoon peak heating hours. Wednesday night and into Thursday morning should be a decent radiative cooling night, with clear skies and light winds. Temps will range from upper 30s across the Bluegrass region to the mid 40s across south-central Kentucky. Some of our traditional cool spots may underachieve forecast lows, so maybe another opportunity for some isolated frost development in the Bluegrass.

===== Friday - Weekend =====

While the mid-week will be quiet in the Ohio Valley, the upper flow transitions across the southwestern US as an upper low deepens and pivots towards the Plains. Deep southwesterly flow will take over by Thursday night, resulting in mild temps for Friday morning. Warming trend will continue for Friday and into the weekend, with temps warming to the low-mid 70s on Friday, and temps surging into the 80s for Saturday and Sunday.

Precip Discussion... As for precip chances, we'll see PoPs make a return to the forecast by Friday morning. The aforementioned upper low will likely be located east of the Rockies by Friday morning, with a cold front stretching to the south into Texas, and a warm front extending out to the east and into the Tennessee Valley. This warm front boundary will push northward during Friday, bringing increased rain chances and isolated thunder to our area. Highest PoPs of Friday will be during the daytime hours. Model soundings are not too impressed with instability profiles, though the shear will likely increase later in the day as a broad LLJ expands into the lower Ohio Valley as the upper low spins towards the Great Lakes region.

We'll remain in the warm sector of the low pressure system through the weekend, with some mid-level vorticity lobes swinging around the parent upper low to provide additional forcing. This will likely lead to additional on and off rain chances through the weekend.
Still don't have much confidence on timing each little disturbance, so will keep a broad brush PoP going for majority of the weekend. If there's any area that has the best chance of being mostly dry this weekend, it'll be the Lake Cumberland region.

Wind Discussion... A breezy period is expected for Friday and into the weekend as southerly sfc winds ramp up. To start things off, we'll likely see wind obs increase by the Friday afternoon hours as the LLJ expands eastward and the sfc pressure gradient tightens. Sfc winds will continue to ramp up for Saturday and Sunday as the pressure gradient remains in place, with each afternoon having high probabilities of wind gusts greater than 30 mph. For Saturday afternoon, roughly 80-90% of EPS members suggest wind gusts greater than 30 mph will be concentrated from Lexington and I-75 and pointing westward. For Sunday afternoon, between 70-85% of EPS members indicate wind gusts greater than 30 mph for the same areas.
Probabilities for gusts greater than 40 mph fall below 40% at this time, but it's worth keeping an eye on in the coming days.

==== Early Next Week =====

Another upper low system for early next week looks to follow a similar track as the late week system discussed above. This will likely bring shower and storms to the region for Monday. As of now, model soundings don't show much sfc-based instability, but will keep tabs on the trends throughout the coming days.

Issued at 645 AM EDT Tue Apr 23 2024

Winds will pick up today in a tight gradient between low pressure crossing the Great Lakes and high pressure over Georgia and South Carolina. Winds coming in from the southwest will gust 20-30kt, especially this afternoon.

Tonight the low to our north will drag a cold front into the Ohio Valley. Light rain and lower ceilings will accompany the front, but flying conditions should prevail low-end VFR. The rain will only last a few hours before the front pushes through, and winds will be much lighter than what we will have seen during the day.
