Over the next 24-48 hours we're anticipating quite the wet and active stretch as our next low-pressure system tracks in from our west. A few isolated showers will be possible this morning, however chances will greatly increase past 8 p.m. today lasting through the overnight hours which may lead to heavy rainfall accumulations and possible flooding concerns.
As we head towards the evening, both upper level forcing and atmospheric moisture will continue to increase which will eventually lead to widespread showers across the region. At times heavy downpours will be likely this evening however our chances for thunderstorms will stay on the lower side. However, with such a large amount of atmospheric moisture present heavy rainfall will remain possible with a half an inch or more of precipitation possible in spots by tomorrow morning. The main concern tonight will be flash flooding due to rainfall over the last few days including any additional rainfall we see later.
As showers begin to weaken towards the morning, cloud cover will stick around early tomorrow morning. We'll be keeping a close on this cloud cover because it will heavily determine how much atmospheric instability, we can develop into the afternoon. Any atmospheric instability that develops will be the fuel for thunderstorms into the afternoon tomorrow with the possibility of a few severe thunderstorms. As of now the Storm Prediction Center has the state line outlined in a slight 2/5 with damaging wind gusts, large hail, and a few tornadoes possible.
With the afternoon round both the intensity and likelihood of showers and storms will depend on instability as previously mentioned. Even if we don't see storms around 3-6 p.m. chances for precipitation will continue to increase towards the late evening tomorrow night as the cold front comes in which may force even more thunderstorms. Depending on how our atmosphere evolves over the next day, we could see very high rainfall totals in local areas with nearly 1-2" possible in some areas.
