000 NOUS46 KMFR 011227 PNSMFR ORZ026-020030- Public Information Statement National Weather Service Medford OR 527 AM PDT Thu Apr 1 2021 ...MEDFORD OREGON WEATHER REVIEW: MARCH 2021... "In like a lamb, out like a lion", so the saying goes for March weather. Well, March 2021 was in like a lamb, and out like a lamb too, although there were a few "lion" systems to move through the area during the month. Overall, the month ended with cooler than normal temperatures and below normal precipitation despite the fairly active weather. March 2021 started off under high pressure with dry conditions and above normal temperatures. Then a strong trough moved through the region on the 4th and 5th, which brought strong winds and more beneficial rain and snowfall. This system brought the strongest winds of the month for the Rogue Valley with a maximum wind gust of 44 mph on the 4th. Periods of active weather, followed by brief periods of high pressure continued through much of the month. Another system passed through the region from the 9th through the 11th. This system was weaker than the previous, but still brought gusty winds to the area. Another, much colder, system affected the area on the 14th and 15th. Snow levels initially started out at around 4500 ft, then quickly lowered to 1500 ft behind the front with a few inches recorded in the foothills around Medford and Ashland area. This system brought one of the coldest March air masses that the region had seen since 2012. The high temperature of 46 degrees at Medford on the 15th was the 4th coldest high temperature on record. Temperatures moderated over the next few days as a brief period of high pressure moved through the area. Another windy system affected the area on the 18th. Precipitation with this system was focused along the coast, especially along the Curry Coast. Downsloping from these strong winds significantly limited precipitation in the Rogue Valley and only 0.01" was recorded with this event. After this system, high pressure developed over the eastern Pacific, leaving the region under northwest flow. Weaker systems moved through the area during the week of the 21st, but precipitation was focused along and west of the Cascades, especially north of the Umpqua Divide. High pressure dominated for the end of the month with a thermal trough at the surface, and this brought above normal afternoon temperatures. However, a cold front pushed through the area on the 29th, and afternoon temperatures dropped by 15 to 20 degrees over a 24 hour period. The month ended on a warm note with the warmest temperatures of the year so far occurring on the last day of the month. 81 degrees was recorded at the Medford Airport, and this was only 5 degrees shy of the record for the day (86 degrees in 1911). This was common across the area with other climate sites also recording high temperatures within 5 to 7 degrees of their daily record. The average temperature for the month was 47.7 degrees, which is 0.7 degrees below normal. The average maximum temperature was 60.4 degrees, which is 0.9 degrees above normal. The average minimum temperature was 34.9 degrees, which is 2.2 degrees below normal. The highest temperature for the month was 81 degrees which occurred on the 31st. The lowest temperature for the month was 30 degrees which occurred on the 1st and 23rd. There were 14 clear days, 11 partly cloudy days, and 6 cloudy days. Total precipitation for the month was 1.47 inches which is 0.24 inches below normal. Total precipitation for the water year (beginning October 1st) is 11.86 inches which is 1.93 inches below normal. Calendar year precipitation is 5.32 inches which is 0.83 inches below normal. The average wind speed for the month was 5.1 mph. The fastest recorded two-minute wind speed was 36 mph from the southeast which occurred on the 4th. The peak wind was 44 mph from the southeast which occurred on the 4th. The highest pressure for the month was 30.42 inches on the 30th. The lowest pressure for the month was 29.70 inches on the 3rd. $$
