Special day on tap.
850 mb temps have trended a degree or so slightly warmer than 24 hrs ago. With WSW flow and mixing towards 850mb away from southern and eastern coasts, and l unseasonably warm temps aloft (+1-2 STD 850mb temps), have continued to lean to NBM 50-75th percentile and HRRR. With temps already starting near seasonable highs this morning, widespread high temps in the upper 70s to mid 80s are expected away from southern and eastern coastal
areas (greater maritime influence). This will result in temps approaching records for the date for a few spots. NBM deterministic is still generally running in the lower 25th
quartile of guidance for max temps today, which appears to be low based on the anomalously warm airmass.
