Here's a quick video showing the thunderstorm that sat over Bridgeville, Delaware yesterday (Monday) and dumped over 4 inches of rain in less than 1.5 hours. Data from our weather station helped the US National Weather Service Philadelphia/Mount Holly confirm the extreme rainfall rates shown by the radar, and the subsequent Flash Flood Warning they issued yesterday.

Delaware remains in a statewide Drought Watch due to long-term deficits in precipitation, lower than normal streamflows, and below average groundwater conditions. To assess water availability in the state, CEMA and the Delaware Geological Survey developed the Delaware Water Tracker. This comprehensive tool compiles groundwater levels, precipitation, and evapotranspiration in one location.

Following up on last week's heat wave, several stations in the DEOS Network AVERAGED 100+ degrees for their maximum daily temperatures from the 1st through the 3rd. That's extremely unusual, and has only happened 6 times since 1893 in Dover, with the last time occurring in July 2010.

If you we're wondering why Kent County looks a little hotter on the map than New Castle or Sussex Counties, it's likely an effect of the ongoing drought conditions, where Kent County has been the driest part of the state lately. The easiest way to explain this is that a drier surface converts more of the sun's energy into sensible energy, or energy you can feel, than a wetter surface. Meanwhile, wetter (or less dry) areas tend to split the sun's energy more evenly between sensible energy and latent energy, which is basically evaporation and transpiration (water released from plants during photosynthesis).

One word describes how this feels: YUCK! Be careful outside today. PLEASE don't overdo it!

The DCO has released their 2025 Annual Climate Report for Delaware.

Delaware experienced six consecutive months of above average temperatures (February to July) in 2025 as well as seven months with drier than normal conditions. All portions of the state experienced some months with severe drought conditions.

Look at the incredible temperature gradient between our coastal DEOS stations and our DEOS stations several miles inland. That's a 34 degree difference between Bethany Beach and Dagsboro!

This type of situation occurs this time of year when we have a warm air mass with strong southerly flow moving in. The influence of the much colder Atlantic Ocean usually only extends a mile or so inland (at most) when the wind ditection is just right.

Our streak of days with snow covering the ground has come to an end in most parts of Delaware. After 24 consecutive days with snow cover at the New Castle County Airport, the grass is visible again. The 24-day run with snow on the ground is the 4th longest snow cover streak on record in Wilmington. Only 1978 (36 days), 1961 (31 days), and 2003 (27 days) have seen longer streaks. Now the question becomes—how long until the next flakes begin to cover the ground?

We're proud to announce the availability of the Climate Projections for Delaware report we recently completed with support from Delaware DNREC Climate, Coastal and Energy . Check out this article at https://www.udel.edu/udaily/2026/february/delaware-climate-change-extreme-weather-storm-center-environmental-monitoring-analysis/ some background or if you'd like to download the report, visit the project page on our CEMA website at https://cema.udel.edu/projects/de-2025-climate-change-projections.php.

The freezing temperatures streak FINALLY ended yesterday, as temperatures around the state "surged" into the upper 30s and lower 40s. Wilmington's streak of 10 days tied for 5th all-time at that location, while Dover's streak of 9 days tied for 7th all-time for its period of record. We've put together some graphs and Q&A's to help explain this recent cold streak and to put it into some perspective.

There's more cold air on the way this weekend, as the general weather pattern stays pretty much locked in over the eastern United States for at least the next week and probably longer.
