• Frost and Freeze in Maryland, April 10, 1997$1.5 million · 8 eventsA record cold arctic air mass overspread northern and western Maryland overnight on the 9th and 10th, dropping temperatures into the upper teens to lower 20s across the entire area.
• Frost and Freeze in Maryland, April 4 to 5, 201616 eventsA reinforcing strong Arctic cold front moved through the region, with temperatures dropping well below freezing, resulting in widespread freeze.
• Frost and Freeze in Maryland, April 5 to 6, 201616 eventsArctic high pressure built into the region behind a departing cold front, with temperatures dropping well below freezing, resulting in widespread freeze.
• Frost and Freeze in Maryland, April 9 to 10, 201616 eventsA deepening upper level trough swung through the region during the day. As the trough axis set up east of the region, strong cold air advection on northwest flow resulted in temperatures across the area dropping well below freezing.
• Frost and Freeze in Maryland, April 10, 200715 eventsUnseasonably colder air moved over western Maryland on April 4th and spread east through April 10th. Clear skies and light winds overnight allowed temperatures to fall into the upper 20s to lower 30s.
• Frost and Freeze in Maryland, April 9, 200715 eventsUnseasonably colder air moved over western Maryland on April 4th and spread east through April 10th. Clear skies and light winds overnight allowed temperatures to fall into the upper 20s to lower 30s.
• Frost and Freeze in Maryland, October 30, 201115 eventsCanadian high pressure provided chilly conditions during the morning hours of the 30th. Minimum temperatures during the early morning hours range from the mid 20s to lower 30s.
• Frost and Freeze in Maryland, November 10 to 11, 201715 eventsCanadian high pressure shifted overhead, causing temperatures to drop well below freezing.
• Frost and Freeze in Maryland, November 2 to 3, 201915 eventsHigh pressure overhead caused radiational cooling on the morning of the 2nd and 3rd.
• Frost and Freeze in Maryland, April 16 to 17, 202015 eventsCanadian high pressure ushered in chilly conditions late on the 16th through the early morning of the 17th. Temperatures dropped below freezing across most of Maryland where the growing season was in effect.
• Frost and Freeze in Maryland, March 26 to 27, 201214 eventsA northwest flow around Canadian High Pressure caused temperatures to drop below freezing across most locations.
• Frost and Freeze in Maryland, October 19, 201513 eventsHigh pressure built up over the region, resulting in light winds and clearing skies. Strong radiational cooling led to widespread temperatures dropping below freezing.
• Frost and Freeze in Maryland, November 6, 201212 eventsHigh pressure over the Mid Atlantic led to temperatures to drop below freezing overnight.
• Frost and Freeze in Maryland, October 25 to 26, 201312 eventsHigh pressure was located across the Mid Atlantic and clear and calm conditions led to temperatures to fall below freezing. This ended the growing season in many locations.
• Frost and Freeze in Maryland, April 17, 201412 eventsHigh pressure was centered over Maine and extended down to the Mid Atlantic. Calm and clear conditions led to the second night in a row with temperatures below freezing.
• Frost and Freeze in Maryland, May 9 to 10, 202012 eventsHigh pressure settled over Virginia, allowing winds to go calm across the region within what was an already very cold ambient environment for May. This lead to a widespread freeze across central and western portions of Maryland.
• Frost and Freeze in Maryland, April 21 to 22, 202112 eventsA Canadian high pressure, light winds and clear skies resulted in widespread freezing temperatures late at night through early in the morning.
• Frost and Freeze in Maryland, October 24 to 25, 201311 eventsAn upper level trough was located across the region resulting in colder than normal temperatures. During the evening, calm and clear conditions led to temperatures to fall due to radiational cooling.
• Frost and Freeze in Maryland, April 7, 200710 eventsUnseasonably colder air moved over western Maryland on April 4th and spread east through April 10th. Clear skies and light winds overnight allowed temperatures to fall into the upper 20s to lower 30s.
• Frost and Freeze in Maryland, April 8, 200710 eventsUnseasonably colder air moved over western Maryland on April 4th and spread east through April 10th. Clear skies and light winds overnight allowed temperatures to fall into the upper 20s to lower 30s.
• Frost and Freeze in Maryland, October 13, 201210 eventsHigh pressure over the Northeast led to temperatures to drop in the Mid Atlantic to the upper 20s and low 30s.
• Frost and Freeze in Maryland, October 29, 20059 eventsFrost conditions occurred during the early morning hours of October 29. Temperatures ranged between the lower and middle 30s across the area, including much of Maryland, northern Virginia, and the Eastern Panhandle of West Virginia.
• Frost and Freeze in Maryland, April 16, 20149 eventsHigh pressure was located across the Ohio Valley and clear and calm conditions led to temperatures dropping to below freezing across the Mid Atlantic.
• Frost and Freeze in Maryland, October 26, 20169 eventsCanadian high pressure was overhead leading to freezing conditions early on the 26th.
• Frost and Freeze in Maryland, November 13, 20169 eventsHigh pressure overhead caused mainly clear skies and light winds. Radiational cooling led to a freeze.
