Sunny, dry, and pleasant for the last weekend of May

The persistent pattern which brought a multi-day episode of clouds and much-needed rain has moved on, with the result being a pleasant weather forecast for the last weekend of May. This Friday morning began with temperatures in the upper 50s and will feature afternoon highs in the low 80s under sunny skies. Those readings are pretty much spot on for late May averages in Mecklenburg County.

Saturday will look much the same but with a few more clouds as yet another cold front dives south across the region. Following afternoon high temperatures in the low 80s, cooler air behind this next boundary will drop tomorrow night's local thermometer readings to near the 50º mark. Sunday will thus begin a bit chilly before warming into the upper 70s under sunny skies.

This new weather pattern will also stick around a while, dropping cold fronts south from the Great Lakes region which will continue to usher in cool dry air. This is known as an "Omega Block", with upper air currents resembling that Greek letter's shape:

The upside to this pattern is continued pleasant weather conditions. The downside is that, despite a mention of "damp" conditions across the Eastern U.S. per the graphic, rainfall needed to continue alleviating the local drought conditions will be scarce for a while.

One last hurrah for clouds and rain, then cooler and drier conditions arrive

Today - Wednesday - will be the final day of this late May extended stretch of clouds and rain. The latter has been very welcome given the drought situation, and more precipitation over the next few weeks would be helpful. However, one factor which may not be as welcome is the humidity. Dew points in the 70s bring a very uncomfortable feeling to the air:

Today's high temperature in the mid-80s doesn't sound bad until the stickiness is factored in. A stationary front which has bobbled north and south across Virginia since last week is hung up near the DC area this morning. That boundary will dip southward later today ahead of a vigorous cold front diving down from the Great Lakes region. 

The overall result will be more showers and storms, with most of that activity reaching Mecklenburg County near or after the dinner hour. The Storm Prediction Center has the local area under a Marginal Risk - level 1 of 5 - for severe weather today, so stay attuned to weather sources and heed any warnings which are issued.

Cooler and drier air will move in behind that cold front via northerly breezes. Thursday looks to be sunny with afternoon highs again in the mid-80s...but without the sticky humidity. There may be a stray shower or storm tomorrow, but those will be few and far between. By dawn Friday temperatures will drop back into the upper 50s ahead of what looks like some very nice weekend weather.

A quick Memorial Day look at the weather

 Those low clouds will stick around today - Monday - through much of Tuesday, with another inch or more of liquid collecting in local rain gauges by tomorrow evening. Temperatures are edging back up toward late May averages, with afternoon highs both days peaking near the 80º mark. Thunder rumbles could occur either day, but nothing severe is expected.

Meanwhile, today is Memorial Day, a time to reflect and remember those who have died during service to our nation. At 3:00 p.m. local time there will be a National Moment of Remembrance, a minute of silence. Even though today's weather conditions may hinder planned outdoor activities, take time to remember and honor the fallen.

The warmup commences, but the clouds and rain stick around for a while

As mentioned in Friday's blogpost temperatures in the midst of a cold air damming (CAD) event - like the current one across the Piedmont - can be tricky to forecast. Saturday's highs in the upper 50s to near 60º around Mecklenburg County were a good ten degrees lower than anticipated. Today - Sunday - that CAD setup looks to finally start breaking down.

The high pressure center over New England which was reinforcing the cool northerly wind flow is moving off the coast this morning. That will swing this morning's winds around out of the south later today, allowing temperatures to climb back toward late May averages. This afternoon's high temperature will top out in the mid-70s despite persistent cloud cover, although sunshine may peek through a few times before sunset at 8:22 p.m. in Clarksville.

Despite unfortunate timing which has marred Memorial Day weekend plans, the rainfall has been very beneficial. The left panel below shows recent rain gauge totals while the right panel is a forecast of additional precipitation through this coming Friday morning:

Daylight hours today will be mostly dry, but more showers and perhaps a rumble of thunder will arrive after dark. 

Sunshine will continue to be scarce through midweek as another cold front approaches and stalls out across Virginia. The next day with "partly sunny" in the forecast is Thursday. However, temperatures look to be more reasonable for this time of year with afternoon highs again climbing above the 80º mark.

Sweatshirts to shorts and back again: May 2026

The weather the first couple weeks of this month seemed like it would never warm to spring-like levels. Then the 90s showed up as an uninvited guest last week, bringing shorts and t-shirt conditions. Now, thanks to Thursday's backdoor cold front and the resulting cold air damming (CAD) wedge it's back to sweatshirts for a couple of days. That's May 2026 weather in a nutshell.

Temperatures dropped like a rock as that boundary pushed south across Mecklenburg County late Thursday afternoon, bringing showers and thunderstorms. Rain totals across the area ranged from 1.92" in Clarksville and 2.26" in Chase City to a somewhat miserly 0.30" for South Hill. Any and all precipitation is welcome, however, given the increasingly concerning drought conditions.

Today (Friday), local thermometer readings look to top out only in the low to mid-60s under cloudy skies. The cloud cover will stick around throughout the upcoming Memorial Day weekend, with showers and storms possible each day. Here's the NWS Wakefield outlook for rain totals through 8:00 pm Sunday:

Monday, Memorial Day, will also feature chances of rain as yet another slow-moving cold front crosses the Appalachians.

Afternoon high temperature forecasts for this weekend could be a bit tricky, as these CAD events can be stubborn to dislodge. Saturday will also be cool, with afternoon highs likely only touching the 70º mark. Sunday's forecast high is in the low 80s, but the actual afternoon maximum may be a few degrees lower than that. By Monday the low 80s are more likely.

Record setting temperatures Wednesday(?), but relief is on the horizon

Today - Wednesday - could bring record high temperatures to a few sites. Here's a prototype map from the National Weather Service showing such possibilities (red numbers) east of the Blue Ridge:

Mecklenburg County localities will see another day of afternoon temperatures topping out in the mid-90s. The good news is that dew points are in the reasonable range, so the overall humidity will stay just below the "miserable" range.

Thursday features a significant change in this summer-like heat as a cold front slowly presses south and east. Most of tomorrow will be sunny and warmer than average again, but temperatures will halt their daily climb at the mid-80s. Clouds, showers, and perhaps a thunderstorm or two will arrive as that boundary finally enters the county during the late afternoon hours.

The weather for the Memorial Day weekend will involve a somewhat rare late May cold air damming setup. Temperatures could feel a bit chilly after this week's heat, and some very welcome rainfall is in the forecast. That's probably not what most folks would desire for a holiday weekend, but the parched ground, dwindling creeks and streams, and the air conditioning bills will appreciate it! 
 

Increased heat risks to begin the work week

Today's (Monday's) forecast high looks to be in the mid-90s, with those readings likely to be repeated Tuesday. The National Weather Service's Heat Risk page has Mecklenburg County in the "Major" impact category both days. As a result heat safety practices will be important:

Today and tomorrow will feature sunny skies and southwesterly winds, both of which are factors contributing to this heat. Overnight temperatures will only fall into the upper 60s at most sites, an indication that humidity levels are also increasing. These conditions are typical of mid-summer, but given that the first half of May has been relatively cool this surge of early season heat and humidity will stress people and animals. 

Relief is on the way Wednesday night in the form of a cold front. That boundary will stall nearby for several days, fostering showers and thunderstorms which should bring much-needed rain for the area. Until then think cool thoughts!
