March 20 starts with a dry, mostly sunny morning with temperatures rising from 35°F to the low 60s, but conditions deteriorate in the evening with likely rain showers, gusty winds up to 28 mph, and precipitation chances reaching 66% by 7–8 PM. Morning driving is favorable, while evening travel carries moderate risk.
- 01 Early morning temperatures (35–37°F between 7–8 AM) are near freezing, raising a minor risk of residual ice on untreated surfaces.
- 02 Rain showers become likely starting around 7 PM (61% probability), with the highest precipitation chance (66%) between 8–9 PM.
- 03 Wind gusts up to 28 mph are forecast during the daytime period and up to 26 mph overnight, which can affect vehicle handling, especially for high-profile vehicles.
- 04 Humidity is high (85%) in the early morning hours, which combined with near-freezing temps increases the chance of slick spots on bridges and overpasses.
- 05 No active weather alerts are in effect for this date.
- 06 Visibility data is not provided — some uncertainty remains regarding fog or reduced visibility, particularly in the early morning given the high humidity (85%) and near-freezing temperatures.
**Morning window (9:00 AM – 11:00 AM):** Safest time to drive. Temperatures have risen above freezing (41–49°F), skies are mostly sunny, winds are light (5–7 mph), and precipitation chance is negligible (2%). Ice risk from the overnight cold has largely dissipated by this window. **Evening window (5:00 PM – 6:00 PM):** If evening travel is necessary, aim to complete it by 6 PM before rain showers become likely. Precipitation chance is still relatively low (25%) at 5 PM, temperatures are mild (62°F), but be aware that winds are picking up to 16 mph with gusts near 28 mph. Avoid driving between 7–9 PM when rain is most likely and heaviest.
