DISCUSSION

Issued at 121 PM CDT Sat Mar 14 2026

Surface low pressure in Wyoming has warm front extending east/southeast into Kansas. This front has been slower than anticipated, thus keep a more southeast wind across north central Kansas and south central Nebraska. High clouds also streaming east off the front at this. The slower movement, winds and clouds and held temperatures back a bit today though Cambridge did manage to reach 70 degrees.

The warm front will make some progress north and east but may not clear the entire area, nonetheless its a mild evening for the area. Weak lift as the upper trough moves closely could trigger some spotter virga/light showers for some areas this evening though the risk for measurable precipitation is very low given the dry atmosphere. Though not in the forecast, there may even be a lightning strike northeast of Grand Island late his evening with some mid-level instability.

Honestly, the main story is the wind overnight through Sunday. Moved up the start time of the High Wind Warning to 3 AM to cover the potential gust above 55 mph along the initial cold frontal surge, which will rapidly move across the forecast area between about 2 AM and 6 AM. The winds only increase from there during the day Sunday and have actually increased wind gusts to the 65 mph range, and I wouldn't rule out a 70 mph report, especially if some more clearing can take hold. Aside from the wind, some light snow will skirt across the northern/eastern areas. Right now, snow amounts would be very light and not amount to much, but with the high winds visibility would be reduced, especially north of Nebraska Highway 92 for a time. Again, probability of even an inch of snow is very low. Skies may start to clear late Sunday afternoon from the west. If that clearing starts early, that could allow for winds to mix down even more. Also, temperatures will go nowhere Sunday and probably drop during the day. What a shock to the system.

The High Wind Warnings goes into Sunday evening, but after 9 pm winds will slowly drop off, through remain gusty through Monday morning. The main story by this time will be bitter cold wind chills overnight Sunday and early Monday, well below zero for most of south central Nebraska and north central Kansas. Temperatures do rebound a bit Monday with sunshine but will still be 15-20 degrees below normal.

The warmup starts on Tuesday.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1227 PM CDT Sat Mar 14 2026

For KGRI/KEAR Airports:

Very active weather for aviation interests, especially later in the forecast period. Initially, VFR conditions are forecast today and through the evening hours with increasing high clouds. Winds will veer a bit with time and increase slightly.

As the evening progress, an upper wave will approach, and with a bit of moisture, could spark some brief, high based showers through both airports. At the same time, winds off the surface with increase dramatically for a short time resulting in low level wind shear (LLWS) near 50kts within 1K AL. Those winds will scream in from the south/southwest as the surface decouples.

The LLWS doesn't last long, as rapidly moving cold front rips across the area in the 07-08Z time frame. Deep, strong flow behind the front will surge winds from the northwest, possible gusting close to 45kts. That flow only strengthens with gusts around 50KTS through the morning, if not higher. MVFR ceilings will quickly fill in. There is at least a small chance of a brief period of light snow which would team with the wind to lower visibility should it arise. Areas of blowing dust due to the dry conditions (assuming limited snow) may also reduce the visibility with the high winds. Winds will favor a bit more northernly directly with time Sunday morning.

FIRE WEATHER

Issued at 305 AM CDT Sat Mar 14 2026

Far western locations of the forecast area will continue to have heightened fire weather concerns late this afternoon/early this evening. A Red flash Warning remains in effect along and west of Highway 281, but within that area its really along and west of Highway 183 where relative humidity will be the lowest. Winds are a little suspect at times, but at this point with fuel conditions, a Red Flag Warning is quite worthy. Conditions probably won't reach criteria closer to 281 but will still be at least near critical and supportive of fire growth should one develop. One wild card is the passing of a few high-based sprinkles or showers early this evening that could pose some erratic wind issues at times, especially as fire containment continues in western Dawson county.

High winds late tonight and Sunday pose a risk as well for fire growth, though there is enough relative humidity recovering, clouds and colder temperatures to keep Red Flag off the table for tomorrow.

Winds will be decreasing Monday but relative humidity will be near 15% even with 40 degree temperatures, so near critical conditions could sneak in there again.

And a brief note for late week. High temperatures 25+ warmer than normal (in the 80s at least) will spread across the area. While it doesn't look overly windy, such warmth will easily support very low relative humidity and potential wildfire growth concerns from Wednesday through Saturday, and beyond.

CLIMATE

Issued at 121 PM CDT Sat Mar 14 2026

From the climate standpoint, the end of the week still looks more like summer than late March. Beginning on Wednesday with the surge into the 70s/80s, and then 80s Thursday through Saturday. For perspective, normal high temperatures late next are 55-59 degrees, and the current forecast is easily 25 degrees warmer. The heat will be driven by an unseasonable strong upper level high pressure system over the southwest United States. The high peaks dead center on the 4-corners early Friday at four standard deviations stronger than normal. We are not forecasting record high temperatures, which are in the 80s to around 90 degrees at this time, but its very reasonable to assume the current forecast could be on the "cool" end by a few degrees given the very dry, warm ground for late March.

The ridge breaks down next Sunday/Monday so the unseasonable warmth could last through the 25th or 26th. So far in March, Grand Island is at its 10th warmest on record. Even with the brief chill coming, Grand Island could start climbing the charts pretty quickly late this week.
