Discussion

There has been rain, heavy at times, during the past couple of days and there will be rain, heavy at times, during the next couple of days…watch out for localized flooding. There are a couple of differences, however, in overall atmospheric conditions that will have an impact today, tonight and tomorrow. First, the overall atmosphere becomes some what more unstable later today leading to an increasing wind compared to earlier in the week and an also an increased chance for a strong thunderstorm. In addition, the overall atmosphere will become colder later today and tonight and this will allow for an increased chance of hail (ice pellets) or graupel (snow pellets) during any heavier shower or thunderstorm right through tomorrow. The weather remains somewhat unsettled on Friday and it takes until later in the weekend to finally settle down to quieter and milder conditions.
