What was once Hurricane Arthur is now an extra-tropical cyclone in the Canadian Maritimes. For the most part, Hampton Roads was spared the worst of the storm. Winds in my neighborhood weren’t that bad. Rainfall only totaled 0.80 in my backyard. Many folks are probably wondering why the storm did not bring worse conditions since it was classified as a category 2 storm. In the past, Hurricanes of similar intensity that passed by to our southeast over the Outer Banks have caused more damage to the Hampton Roads cities. There are several factors that determine how severe conditions will be in any given area when a hurricane comes through the region. Every storm has different characteristics and the structure of  each storm does vary somewhat. Some storms are larger than others. Hurricanes that develop from the tropical waves that travel westward across the Atlantic sometimes are larger storms. Arthur did not develop from one of those tropical waves deep in the tropics. Some storms have strong winds that extend very far from the center of the storm. Some storms have heavier rainfall than others in most or all quadrants. For example, back in 2003. Hurricane Isabel  had a very large area of very strong winds far out ahead of the storm. This was due to a steep pressure gradient between high pressure to the north and the hurricane approaching from the southeast. Wind damage was much more widespread with Isabel. Some folks lost power for several days and even weeks. Rainfall totals were higher with Isabel. In 1999. Hurricane Floyd caused massive stream and river flooding in parts of NC and VA, but it also had weaker winds than expected in Hampton Roads… Now to address the current and future weather. The relatively cool and dry air mass that moved into Hampton Roads this weekend in Arthur’s aftermath is now getting set to move off the coast. A south to southwesterly flow will transport heat and humidity back into our region starting Monday as the high pressure area takes up residence off the southeast coast. Tuesday may be a very warm day with high temperatures possibly reaching the mid to upper 90’s! An approaching cold front may trigger showers and thunderstorms beginning on Wednesday and possibly lasting into Friday. The front is expected to wash out so no real relief from the humidity is expected right away from the front. We’ll see if cooler and drier air will be able to make it this far south and east next week. So, enjoy the pleasant weather today (Sunday) while it lasts! Thanks for reading and have a great day.
