DAYS 1-5 (FEBRUARY 28 – MARCH 4)
On this final day of February 2021 we will be dealing with a minor low pressure system, the second of two to effect the region this weekend. However, unlike Saturday’s which started as snow early in the day in part of the region, followed by rain for most of the region through the day, this system will struggle to do much, putting some rain across the South Coast during the afternoon and taking until tonight to deliver some light rainfall to the rest of the region. The air will be too mild to support any snowfall. After this relatively minor system pulls away in the early hours of Monday, a final band of showers may visit the region during the morning as cold front number 1 of 2 passes by. The air will not be all that cold behind this first cold front, so that Monday itself will be fairly pleasant, temperature-wise, although there will be a gusty breeze. It is when the second cold front, an arctic boundary, arrives from west to east during the evening that the bottom will fall out and the temperature will plunge. The arrival of this air mass may be marked by some snow showers and snow squalls during Monday evening. Snow squalls can quickly drop visibility to near zero with heavy snow, which can also quickly coat the ground and make for slippery travel, even for a while after they have departed. Our arctic air, which will make the second day of March on Tuesday feel more likely the second day of January, will only be around for one day. By Wednesday we’ll see a significant temperature rebound as milder air arrives from the west. However, during Thursday another cold front, this one not quite as strong, will slide through the region from north to south and introduce somewhat colder air once again.
