Portland, Maine – A mid-February warm-up is expected across Maine, with temperatures forecast to run 10 to 20 degrees above normal during the period from Feb. 16–20, according to the NOAA Climate Prediction Center.
The agency’s 6–10 day temperature outlook shows a strong signal for above-normal temperatures across much of the state, including Portland and Bangor. Probabilities for warmer-than-average conditions exceed 60 percent, indicating a high-confidence shift away from typical mid-winter cold.
Under normal conditions, mid-February highs in Maine generally range from the upper 20s to mid-30s. During this warm stretch, daytime temperatures are expected to rise into the upper 30s and 40s, particularly across southern and coastal areas. While not a true spring pattern, the change will be noticeable compared to seasonal norms.
This warmth is part of a larger weather pattern affecting much of the central and eastern United States. Across the Midwest and Mississippi Valley, temperatures may climb into the 50s and 60s, reinforcing what forecasters often describe as a “spring tease” during late winter.
Precipitation outlooks indicate near to slightly above-normal rainfall potential across parts of the Northeast. Combined with melting snowpack, this raises the risk for localized ponding and minor flooding, especially in low-lying or poor drainage areas.
Forecasters caution that this outlook reflects probabilistic climate guidance, not a daily forecast. Cold air can still return later in February, and residents should continue monitoring local forecasts for short-term changes.
For commuters, students, and outdoor workers, the warmer conditions may offer brief relief from winter weather, though rapidly changing conditions remain possible.
