Several Space Weather alerts have been issued by NOAA. Geomagnetic storms are expected and could cause auroras as low as New York. There has been a recent set of CMEs which has caused auroras to be view-able at lower latitudes. The Issue times and severity index of the today’s storms can be seen below:

Issue Time: 2014 Feb 19 1346 UTC

EXTENDED WARNING: Geomagnetic K-Index of 6 expected
Valid From: 2014 Feb 19 0330 UTC
Now Valid Until: 2014 Feb 19 1800 UTC
Warning Condition: Persistence

Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents – Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft – Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio – HF (high frequency) radio propagation can fade at higher latitudes.
Aurora – Aurora may be seen as low as New York to Wisconsin to Washington state.
